Rev210, i was simply refering to Robo's car being set up for street/drag.I have a full whiteline handling kit, with optioned pinapples and camber bushes. I'd like to think my car is set up for circuit/motokahna/drift, so the pinapples have been installed for "all round performance" and not only for "grip", which changes the angle of the craddle.
My initial point i was trying to make was that a well set-up suspension will get you much more than "2 tenths" down the 1/4 mile (as Ash has stated). I believe it will get you closer to 8 tenths or more; as off the line traction/launch is the most crutial element of drag racing.
Also i still say that a solid diff/axle set up (non IRS) will have more traction than IRS, therefore the R31 is better suited. With IRS the best setup would be to have +ve camber at the rears, so that when the car squates, on take off, the wheels will pull in and effectivly have 0deg camber, thus having the full face of the tyre in contact with the tarmac. With my car i have -1deg at the rear (for circuit, etc), so when i launch and the ass end squates, this -ve camber increases, thus resulting in less tyre contact on the road. Having lowered suspension also doesn't help the situation, as there is less travel.
I occationally like doing drags as i do enjoy it, especially with the slicks I dodn't treat it seriously as my car is not set up for it. Just like to get out there and have a blast in a controlled environment :sorcerer: .
