Sequential (Sadev) in a CSR


Recommended Posts

Has anyone here fitted a Sadev (or Quaife) in their CSR? I've been advised by Caterham that "there is likely to be some chassis modification required. The tunnel top also is designed for an H pattern box."

 

Can anyone elaborate on what I would have to do/modify to get a sequential to fit the CSR chassis?

 

What have people done to make the tunnel look best with just the forward/backward motion?

 

Thanks for any help. With a little luck, my CSR Superlight will be shipping from the UK in the next week.

I think you are going to be a first to attempt a sequential in a CSR. All previous CSRs were specified with the Caterham 6 speed to the best of my knowledge.

 

First thing - you have to first clarify which CSR chassis you are trying to work with - swoopy dash version or the standard looking dash version.

 

If swoopy dash then yes there is modification to the chassis needed. From my explorations during a weak moment of mine in the specification of my CSR, I discovered this. As I understood it the gear stick comes up through a fairly narrow "box"/square so you have limited fore and aft movement for a gear stick - not enough for a sequential but just enough for a Caterham 6 speed box. The problem exists not just for the Sadev but also the Quaife sequential. It is still very tight even with the Caterham 6 speed H box. For example, in first gear on my car the gear stick is just touching the chassis cross bar on the dash. I am not aware of any other tunnel top issue other than the the gear stick issue.

 

I am not sure the same issue exists on the regular dash CSR as that area is very much different in how the chassis cross bars are laid out. They are more like an SV and so may accommodate a sequential more readily. It will be a case of test fit and see!

Joe,

 

Indeed I do have a Sadev gearbox in my Superlight SV. As Tom says, I added a Geartronics Paddle Shift kit to the Sadev. Just double the price of the Sadev (ouch) and you will have one fantastic system. Mog-Racing sells a Geartronics setup with all the parts you need to connect the Sadev.

 

With the paddle shifter, the shift lever is eliminated so there is no way you would need to modify your chassis. I don't recall just how far the Sadev gear lever moved, but I don't think it was all that much. I agree with Mike, get it and see.

 

The Sadev has a weight advantage over the Quaife too!

 

If you plan on a lot of street driving, I'd stay with the 6spd. But for the track, WOW is it fun. The Sadev with the flatshift setup worked well for upshifts, but the paddle shift kit is a whole different world.

 

If you want to make the trip to NJ, you are welcome to drive my car before pulling the trigger. Warm weather is just around the corner.

Thanks for the insight, guys! My CSR is coming with the superlight dash. I'm planning to get the pneumatics eventually but wanted to get the car up and running without first. I'll report back with how the installation goes. Maybe I'll be getting the paddle shift earlier than I anticipated!

As a CSR Superlight owner I can say they are great cars on the track. The only thing I am not liking is the undertray aero fairing that does get me very light/airborne over a hump on my local track.

 

Superlight was just a track focused CSR package. You still had the option for one of 2 dash layouts - swoopy with integrated chassis tubes or the traditional flat dash panel layout. Do you know which option you ordered?

 

If you got the removable wheel option then you probably have flat dash and it should be relatively easy to install the Sadev. If you got the swoopy dash with the Rover steering column then be prepared for some chassis cutting for the Sadev. As for the paddles on this swoopy dash steering column then that will be an interesting installation process....I am not sure it is possible given the design.
