elan_fan Posted February 2, 2014 Share Posted February 2, 2014 I changed mine to 22% when I first got the car. It's perfectly ok for road use. Link to comment Share on other sites More sharing options...

Guest Posted February 2, 2014 Share Posted February 2, 2014 thanks elanfan.before i bought my super sprint i drove a ex race k series and the steering was very quick but seemed no problem.the supplier of the quick rack suggest race car on slicks for the 22% and road and track day for the 8%.sounds like the 22% is the one to go for.

myothercarsa2cv Posted February 2, 2014 Share Posted February 2, 2014 You might well have the 8% already... Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2014 Share Posted February 3, 2014 Most (though not all) of the racers I know use 8%. Not sure how much of that is inertia (I've never used the 22% so can't really judge) but certainly don't assume that 22% is necessary for track use.

Drumster Posted February 4, 2014 Share Posted February 4, 2014 Quoting myothercarsa2cv: You might well have the 8% already... As it's an old Supersprint it's fairly likely that he has the old (I think) mini rack which was standard at the time and this will be the now defunct 0%. I went from one of these to a 22% rack and found the handing/response etc to be much improved, however, if you search the archives there are plenty who think the 22% is too twitchy for the roads. Each to their own ...... Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted February 4, 2014 Share Posted February 4, 2014 I'd like a 22%, so if anyone finds it too twitchy, happy to swap 😬 Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted February 4, 2014 Leadership Team Share Posted February 4, 2014 I've had 2 Caterhams and both came with 22% racks, in fact since I bought my first in 1998 I don't think I'd ever driven one with any other steering rack .... until I swapped to an 8% early last year. For road use it's transformed the car, far more positive and directional on the variety of surfaces that are part and parcel of everyday driving, situations where with a 22% I know I'd be fighting the car a lot more. On track it's definitely not as precise but my driving is 90% plus on road so it's probably perfect now. Stu. Link to comment Share on other sites More sharing options...
