Doran Racing NISMO RC suspension parts

BGTV8

It is really a function of varying roll centre I'd have thought ... as changing ride-height will vary the roll-centre - do you agree ??.

Interesting that it is so sensitive though - I would have thought that chassis stiffness as not high enough (unless your cage feeds the front suspension pick-up loads back into the rest of the bodyshell/cage). Maybe Mr Nissan's claims about chassis stiffness are being borne out here.

Let me know what you think...

Front Ride height is going to adjust a number of things. Roll center being one of them as well as Camber, Caster, Toe and weight distribution. 1 turn on an AST coilover is 2mm but you also have to account for were they mount into the lower control arm so likely about 4-6mm in actual ride height change. The weight transfer from that could be as great as 100lbs front to rear but I have not that experienced with the 370z in particular. I do know this much though I am sure the car is stiff because I know how Kevin Doran designs his cars. They are usually some of the best designed cars in the paddock for a number of reasons. I mean after all this is why teams try to steal his designs (cough, Insight Racing) I also know that B.J. isn't just one of the best drivers on this forum but also in the paddock (if not the best). He has an ability to feel changes in the car that would go unnoticed by us mortals but also to other drivers in the paddock. I got a chance to look at these arms in person and they are extremely impressive. I thought the design was on par if not better then the arms that are on the Doran Ford GT-R a car that finished 3rd at LeMans with a Husband and Wife team! As always extremely impressive stuff from the Doran Stable!
