? Shock and spring
- I will say running a R Series QA1 upfront on a Lt1 style spring which is More then 300 if I recall. I would sometimes bottom out on any quick change in road grade. That would have some to do with the type of shock but since the car is near stock race weight on the nose. I would not benefit from a lighter rating on the spring until the car got siginifgantly lighter
As madman said they are quality and made in america.
My car has strange single's all around before it got the Afco double adjustables and the singles were good for 1.36-1.38 average 60's.
Although they were good, the Afco doubles are allowing me 1.29-1.32 average 60's and I still haven't quite got it perfect yet.
That said Madman will not steer you wrong and will be able to give you the settings you need to get it to work right. Just supply him with the pictures and video needed of the car launching so he can get you set-up perfect.
