SK400

Love it! the best diagram ever. thanks much! now i'm all set .. thanks everyone see you on the track soon.

Thanks for awesome and detailed info. I need to install a12 volt outlet to power all of this. I assume any model would do correct? Is there special Caterham magic in installing one? Never know with this car. On a separate note, do you know if these systems could be paired with a Bluetooth or wifi camera? There is a new camera out there called 360 fly (360fly.com) that allows you to film 360 degrees at all time. You can then edit and replay the movie on your phone or computer selecting the angle you want. I tried it last year at limerock. Very cool (seeing me approach, pass, and then pan the view angle following the car I just passed. ). Would be cool to link it to the gps lap timer systems

Guys, Mike, thanks a super bunch for the info. This is most probably the most comprehensive review of all the track GPS lap timer systems out there. This is super helpful. Based on this infor, i think i'm leaning towards the Solo DL system despite poor customer support (heard real bad) . ' Mike - where did you buy your system (especially that you have to specific that it is for the Noble). Also, where do you install the display in your car? thanks again. Sebastien

Thanks both what do you think of Racelogic 10 Ghz GPS unit? looks like a lot more expensive, worth the money?

Friends, I'm looking to install a GPS lap timer system on my Caterham to get ready for a few track events this summer (and to keep up with my twin sister Simon :cooldude:). Does anyone have any recommendations on best or most relevant systems for the money? Very specifically, i'm looking for a rather basic but yet expandable and user friendly / install friendly system that 1) measures and gives in lap timing, best lap, etc 2) downloads to a computer all basic data such as lap time, g force, and basic engine readings 3) could connect to a camera / mic (wire ok but wifi or bluetooth is best) at a later stage Recommendations, pros and cons, are welcome. Thank you all in advance for the help and advice Sebastien

guys 2016 usa7 debauchery at njmp... I'm in. May have very limited changes this yr and will focus mostly on tuning the front suspension to keep up with my twin R400 brother Simon. Postponing the race to more horsepower to 2017 ... still eyeing 290 hp at the crank .. but thats an aspiration. Lets first get through 2016 season. Talk soon

Mike, Tom, friends What a terrific event! A huge thank you for such a phenomenal organization and for such a warm welcome as usual. It was a real pleasure seeing everyone again this year, even if it was for a short Sunday in my case. .. worth every minute of it. I truly enjoyed pushing the driving limits along with Jeff, Mike^2, Simon (my red R400 brother from another mother), and Tom and experimenting with very late breaking.. just fun times. I just wished I could have spent more time with all of you over the long weekend but it will have to be for next yr. Hopefully with my wife Kelli who would like to give it a try.. Thanks again for the great event. talk to all very soon... thanks!!!!

Greetings everyone well.. sad news on my side, unfortunately my wife's Grandmother just passed away and the funeral is on Friday. I will probably miss the go-kart event and Friday activities (Tom, there you go, you won't have to fight too much to get in front anymore..). I'll see what I can do to join the gang on Saturday and or Sunday (day trip from CT) but all depends on the moral at home and how my wife's mom and the rest of the family are holding up. Terrible timing I know ... and sorry I will most probably miss the bulk of the fun but have to take care of the family. Let's see how things play out. I will keep you updated. talk soon PS: I have new 13" Apollo rim and ZZR tires and just switched to aersocreen.. the car looks great!

Three questions: - JeffS.. will you be joining us?? we will miss you if not around! - Mike .. also potentially interested in locked up garage option only if readily available. Is this still an option? - does anyone has an AIM Smartycam GP and Solo DL data logging system for sale? would love to have at least a basic system installed thanks!

CarMan, I ll try to swing by on the 19th but unsure Tom / KitCat, to answer your question on Toe, I had opted for very slight toe in for high speed track. That said, the car lost its fun steering factor (took It for a drive on local roads last weekend) so thinking on opening up the toe a bit to increase steering responsiveness (neutral or +0.2 deg max). The increase negative camber has changed the front feel of the car and I have no clue how the new setup will handle on the track. .. I have an opportunity to drive on the Monticello track this weekend so I'll report back. Wish me luck!

Love it. Thanks for sharing the pics. I getting to know George Alderman and his son Paul pretty well as they helped me finish and figure out a few quirks with my car when I built mine. I'm in touch with them now to see if they could help me build another engine (the eternal HP quest). Very good guys. Indeed, why don't you come and join us at NJMP the weekend of July 4th?

Tom, you are right on both fronts... but all good fun and for fun times. Keeps me on my toes and a good way to learn. Kelli took the car for a spin last weekend, it was wild! She was a bit afraid of stalling the car so she was a bit heavy on the gas and quick on the clutch at times.. funny (sexy I admit) seeing her fish tailing at intersections. :auto:. CarMan, did not realize you drove on some of the same tracks I occasionally attend. Would be great to connect and / or synch up. I live CT.

thanks! you realize that I'm going through all this trouble (new tires, adjustments, wind deflector etc.. ) to keep up with you on the track right?

Kitcat, agree.. I think I'll adjust to have neutral toe for that track. Quick (novice) question again.. are the steering tie rods only threaded on the tie-rod-end side? In other words, can I simply loosen the tie rod to tie-rod-end securing nut and turn clock wise / counter clockwise the tie rod to change the toe (eg trying to avoid to disassemble the tie-rod-end from the upright)? I assume the that tie-rods connect to the steering rack with ball joints. Is this correct? Any harm or risk in this approach? thanks a bunch

Eureka! the ball joint remover tool worked like a charm. If careful, you can even remove the ball joint without damaging the rubber gaitor. So started at factory setting with a negative camber of 1.25 ish and turned in 6 turns.. setting the negative camber to 2.75. Can't really go further, i'm at the max of the threads. (curious how folks get to negative 3.5). so now, i'm at 130 mm in front and 145 mm in the back As for toe, i'm now right around 1 degree toe out (changing the camber changed the toe). Do you think it too much? feels like i need to reign the toe back in a bit to toe out of 0.5 or so. I've left everything else equal eg bump steer and castor. thanks!

So I ordered all the tools suggested. I'll attempt (again) this weekend. In the meantime, I started to drive with the new ZZRs around town. the car feels different already, perhaps because the front wheels are slightly narrower and my rake is way off. The Steering feels more twitchy and responsive. Kind of cool.. but not sure how this will do on the track.. With all of your recommendations, my goal is to aim at a) 120 mm front clearance (versus recommended 145 mm for the street and caterham academy rules. BTW, that's what I had with my CR500) b) 2.75 or 3 degrees of negative camber to be able to interchange the ZZRs with the CR500 15", and 15 mm of rake to max weight distribution on the front end. I'll do all of this with 150 - 160 lbs ballast in the driver seat (4 bags of 40 lbs wood pellets). Let's see what this setup shakes out on the track. As an aside, I really got tired of cleaning the streets for the city, picking up all sorts of debris and rocks because of the sticky tires. So I went to a custom shop and had quasi the entire car protected with the transparent stone guard film. Can't barely see there is a film on the car... and I don't feel as bad when I see (and hear!) rocks flying. Strongly recommend it .

Really?! There is no other more graceful way? A pusher and puller? A dentist tool? Calls for an invention. Removing the top wishbone is not completely crazy if it helps save some banging. Let me know if you hear of any other method to help. Thanks guys.

I bought the ZZR tires from Roger Kraus as suggested by Mike. Roger was a table pounder for these tires. I wanted to go down and try 13" on my car so opted for the R620 setup (Apollo wheels and 215/55/13 in the back and 185/55/13 in the front) honestly without more thought going into it. But the swap from my 15" CR500 is not a straight forward swap .. the front wheel are 1.15" smaller in diameter and it throws the suspension setting and rake angle way off. On a separate note, i tried to adjust the camber this weekend but to no avail... got stuck at trying to loosen up the upper ball-joint from the upright but ended damaging the rubber gaitor.... Any tool or advice on how to remove the ball joint from the upright? officially standing in my way of setting up the car the right way .. and I have one more weekend left before trying Monticello. thanks !

Thanks a ton Tom. I just installed my new 13" Apollo avon ZZR tires combo (looks great!). However the front tires (185/55/13") are probably 3/4 inch or 1" narrower than my stock 195 Avon CR500 15" and my carbon fiber clamshell fenders look too wide for this new tire /rim combo. Should I be looking for narrower carbon fiber clamshell fenders and perhaps wingstays. Does such thing exist? Also, any thoughts on the recommended front camber angle for these Avon ZZR tires? Simon, i'll look this weekend and send you a PM if I can figure it out. I have the cosworth dry sump.

Greetings Can someone remind me: 1/ rake angle: what is the recommended front and back chassis to road clearance? and where on the frame is the height measured at? 2/ camber angle: on the post 2006 superlight models, what is the camber angle change from one full screw turn of the tie rod end into the upper A arm? any front camber suggestion for 13" avon ZZR tires ? 3/ tool to adjust spring compression: any recommendation on what tool to use? thanks a bunch everyone

Curious.. I believe I have a 10 or 13 row oil cooler from factory with my R400... pretty sure exactly the same supplied on the R300 model. I do run 5W50 Castrol as Jon Nelson suggested and so far so good (hope I did not jinxed myself). I never checked oil temperature although I noticed a drop in pressure (not too serious but noticeable) after a long track event (and I push the revs). I heard pretty standard with duratecs. I do have a cosworth dry sump though.. wonder if that helps keep oil pressure at a minimum protecting the engine

Oh my. Simon.. 700 miles on the car and already blew up an engine? Truly sorry to hear that. Will you be able to rebuild in time for the event ? I don't want to be the only red stripped r400 on the track!! Way too much attention. Main trying to rally two to three other Caterhams / stalkers from Connecticut to come down and have fun with us (Neil, Paul, Steve... Yes talking about you). I need some help from you all to encourage them to come (and for Neil to rebuild his engine in time) We all know they ll have loads of fun.

Mike, Tom, Looks like I will be coming with the whole family... eg: at a minimum my wife, and maybe the two kids and.. yes the AuPair! the Kids and AuPair will probably be with us for a few hours and then explore the area etc.. One question thought.. my wife wanted to try the car on the track for a few laps. (awesome wife right?). Do you think she'll be able to follow one of the instructors for a few laps the same way I did last yr? Do we need to do anything special or just play it by ear once we are there? thanks!

Xcarguy, seeing this now and late to the thread.. Truly sorry about the accident and the loss but happy to see that you are back on the forum. Rest well. Hope to see you soon back on the road.

Not having much luck. Do you have a sense of the Max resistance I should see between an instrument and the ground using an ohm meter to determine if I have a bag ground? Thanks
