Our Hero, cheerleader and already driver!

Packed and ready to go on my road adventure…. Leaving tomorrow at 5 am.

i can’t believe there are 57 pages of motorsport regulations. Someone actually took the time to write this down. Impressed.

Thanks Croc I’m not too far away from the recommend setting but with two differences: neutral front caster vs max negative as you suggested and rather stiffer rear arb. What front toe do you run? Also, I assume you have the standard spring front and rear? I bought the Garyline setup kit. Hope to get it before departure so we can have a bit of fun tuning the car.

As in thinking about it, I also redid my LSD with sintered plates etc, new preload. The effect of the refreshed LSD could be to have more understeer at mid corner especially in lower speed turns. Considering a bit more rake or caster on front. But let me know your thoughts.

Need a bit of advice in advance on handling. I had dialed in my car pretty well in the past, but since i've installed the -2.5 degrees rear camber ears, i find it to push a bit much at entry and middle of corner grip. (understeer). what i read online and from various caterham racing blogs is to go softer setting on the rear ARB to allow more rear roll and transfer weight and hence grip to the front. This is counter intuitive from normal car setup so asking for your thoughts. Is going softer on the rear ARB the right thing to do to correct understeer? I also expect to be hitting rev limiter in 6th gear with 25% of the straight left but that will have to wait for next season to correct as i need to change my FD ratio.

Alright. Just registered as well. Saturday and Sunday. Let the weather Gods maximize our weekend days. Wish me luck as I’m gearing towards a 12h car + trailer ride from Ann Arbor, MI. Mike / Tom - Will we be able to drop my trailer on property Friday night? Will attempt and target 6:30 pm arrival for club dinner on Friday. (Let’s see… and will keep you posted as I make progress or not). Talk and see you all very soon!

Making my way slowly registering. hope the weather holds. remind me, do they sell 100 octane at the track and is it ethanol free? thanks

I’m love the reverse psychology but your Jedi tricks will only partly work on me, Master Croc. But agree, I’m running out of excuses… My car should be quasi ready. I’m waiting for the rear brake LED kit from the UK and that’s about it. Seatbelts are new, helmet, hand device etc. Have 4 yr old tires so okay for NJMP (but not best handling) and some slicks I still have not used since I blew the transmission 3 years ago. So in principle, should be ready. I did not have the energy to change the differential final drive ratio this summer so I suspect I will hit the rev limiter on the straight by the time I pass the tower or just after…. also I have -2.5 camber in the rear now, great but too much grip vs front and the car understeers a bit more at entry. I need to tune the balance a bit. But who cares.., she is fun and still very quick, and I would love to see you all again. It’s been too long.

All, trying to make it to this event. It’s a commitment and a half driving 12hrs each way from Ann Arbor MI! At this point 50 percent chance of I can clear a few things from my plate. Croc, Tom - question for you: is the speed at the end of the straight slightly faster or slower given the new shortcut modification on thunderbolt?

All This gearbox is sold.

All I have an original Caterham 6 speed gearbox for sale, OBO. To be clear, the gearbox is now NOT working, with its lay shaft seized, and an open dent in the end of the lay aluminum casing, a common know issue for these boxes with original equipment. I believe tracsport in the uk sells the replacement and upgrade layshaft parts to avoid the issue going forward, parts that are used in racing applications. The casing could be welded or another part procured. Outside of this, the gearbox is good. I’m willing to give this gearbox away for just a little more than shipping to someone who might be interested in a project. This box in a new or used format typically go for thousands of dollars and hard to find. Let me know if interested. Thank you
