Not sure it will fit the previous version of the E4 but looking at both it looks like it will.
Why did you go up in spring rate?
My theory is STIFF and LOW is fast. And where tracks are smooth and have very little bumps, I stiffen up. We run on asphalt Sorex36, so stiffer is good with that config. Might be different with softer compounds.
Been having a lot of handling issues with soft suspension so we stiffened right up to BLUE front and TURQ rear and could see that the car was noticeably unsettled on the track. We gradually reduced the spring rates until the car seemed smoother on track.
Running soft will let the car roll from side to side and tend to bite on the tyres. Whilst sway bar should remove this, I dont feel that the sway systems on the E4 are stiff enough to make a dramatic difference. We run a G4 as well and they are stiffer.
Stiffer suspension seems to give us a flatter ride and car seems a lot happier.
We arent experienced in any way, still experimenting and this is what Ive found to date.
Any suggestion would be appreciated, by no means are my findings final and we are still working our way around the chassis.
