I'm thinking of making a single seater but don't know what steering rack to use. It would preferably be usable straight from the donor with no modification needed and be fairly short between the inner joints. Any ideas?

fiat cinq, is what i believe the road runner used for the sprint r, and it might be the one used in the new haynes single seater book out soon(ish)

But it does depend on uprights and suspension layout, as you don't want to have bump steer.

Was going to make my own single seater, but now waiting for the book to come out don't have the time to design my own chassis.

If your after a single seater body I have one!!!!

Do you happen to know the distance between the inner joints?

Chinq (and Seicento - same part) is the one used in the Haynes single seater and by russbost for the Furore - sure he'll have the measurements to hand.

lhd nova rack shortened slightly.

Porsche 914/912?

contact Martin at MK engineering he even makes his own uprights negating the need for a sierra donor

gb engineering rack? £150 new, 1 turn lock to lock
