I am trying to improve my cars' (AE, SM, CRC) balance without removing steering, which may be drivable but slower...
1.Narrower rear axle width
2.Softer Center Spring/Oil
3.Larger Rear tires
4.Higher ride height (rear slightly lower than front)
5.Softer side springs
6.Thicker side dampening
7.Softer rear tires (I'm down to whites now)
8.Move body back
9.Move weight on chassis forward
10.Speed8 HD body
11.Top rear of center shock positioned closer to center pod pivot
All depends on what you're looking for.....
1. Will reduce the cars tendency to rotate, and will reduce exit steering on power
2. Will give you more forward bite, reducing exit steering on-power
3. Will add side bite, making the car slightly more stable, but more prone to chunking
4. Rake will make the car turn-in less aggressively off power
5. will add side-bite untill you reach the point of diminshing return by going too soft.
6. Slows weight transfer, will make the car less reactive
7. Whites are in general too soft, good forward bite, but lacks side bite. try yellow or grey
8. I never do this, as it really only affects the car at high speeds
9. slows longitudinal weight transfer. You don't really give up overall steering, but you will lose some turn-in
10. If you're normally running Speed 8's this body offers more grip everywhere.
11. I'd actually move the forward mounting point further forward if possible, though I haven't played with this adjustment in years.
HTH.....
