anthony1956 Posted July 11, 2019 Share Posted July 11, 2019 Which one do I have is my question.I guess it's identifiable by the number of turns lock to lock.Anyone know? Edit: 1.9 & 1.7 TURNS RESPECTIVELY from replies below, thanks :-)Anthonyhttps://www.lotus7.club/comment/29164#comment-29164Tazio: "One thing to remember, I believe that the 22% rack only comes in narrow track,, so if your car is wide track you will need the unsightly steering arm extension pieces"but then: "I have specced 22% rack on the car I am building. Caterham assure me that the extensions are no longer needed as they now have longer arms fitted for widetrack.

Regards"but mine was built as a private track car... and the answer is:Product Code: ST47 91>DD>RHD/8%-WID E TRACK/Q.RELEASE from the CKD Kit invoice dated 27/09/2000 R500 Plaque number 38 Link to comment Share on other sites More sharing options...
Englishmaninwales Posted July 11, 2019 Share Posted July 11, 2019 22% rack is approx 1.7 turns lock to lock. Link to comment Share on other sites More sharing options...
Tony Whitley Posted July 11, 2019 Share Posted July 11, 2019 and 8% is 1.9. Link to comment Share on other sites More sharing options...
anthony1956 Posted July 11, 2019 Author Share Posted July 11, 2019 gosh, only 0.2 of a turn different. That's a surprise. Link to comment Share on other sites More sharing options...
StevehS3 Posted July 13, 2019 Share Posted July 13, 2019 Mine has the standard rack and I swapped cars for an hour with a friend’s race car with a quick rack. Neither of us could tell the difference. We both found that strange but if it is only 0.2 of a turn perhaps that is why. Link to comment Share on other sites More sharing options...
Englishmaninwales Posted July 13, 2019 Share Posted July 13, 2019 Possibly makes a tiny difference for 1 corner in the Sprint Championship, (Sawbench hairpin at Wiscombe hillclimb), and that’s about it.....not worth it for a road car. Far better to focus on rack height and bump steer. Link to comment Share on other sites More sharing options...
anthony1956 Posted July 13, 2019 Author Share Posted July 13, 2019 It doesn’t sound like .2 of a turn would allow me to complete a hairpin without regripping the wheel. Link to comment Share on other sites More sharing options...
StevehS3 Posted July 13, 2019 Share Posted July 13, 2019 Makes you wonder why they would bother having the option. Link to comment Share on other sites More sharing options...
Tony Whitley Posted July 13, 2019 Share Posted July 13, 2019 I fitted one to my old car and it transformed how it felt - the usual small movement of my hands became almost telepathic control. When I got my present car I swapped to a quick rack and noticed no difference, I have no idea why. Link to comment Share on other sites More sharing options...
