bump steer: happens going over bumps, pot holes? tracks and autox's are generally not that bumpy.

i was thinking of relocating the whole steering rack to the bottom front of the engine bay and installing a Mustang rack/pinion , relocate the steering arms and knuckles to the front of the wheel hub. rack level with the front LCA's, shorter tie rods. now how do i do this???

strikeflo: yes, the on power corner exits are a 2/10ths killer. did sfr autox from 05 to 10 and can say from numerous times out there that yes, brake late, rotate, point nose, then get on gas. seemed like forever. i'm open diff. i drove a 1.5 diff rsx on the same day autox as my own. slaloms felt better , tighter. and exit sweepers with smooth throttle roll on were nice.

trail brake at Thill? wow ! i did on turn 3 because of the small crest and off camber downhill , mistake for me, rear came out, not violently but at speed way faster than any autox. i caught it

i think i can say that the rsx suspension geometry is fine stock, but to drive it at the limit, you have to be very smooth. put a cup of water in the cupholder smooth.

all this suspension talk made me take a look at my own set up. and i know that it's weak. hks hypermax 6kgfr 9kgrr. these coils are 4 years old and i need a better set in the future.
front springs are weak in that i get slow rebound, i feel the springs do not have enough force to keep the nose level in certain surface depressions.
high speed compression=great ff and rr. low speed compression, not so good. the feel they want to bottom at 10-15 mph over small bumps.
for a daily driver, it's pretty good.

i hope this is still on topic???

it's been years, but this to me makes a DC5 driver more credible as a driver than anything else then.

thank you sir !!!

It might as well be. I'm no shock builder, but I think that high speed/low speed piston disparity is due to the sub-optimal curve our coil-overs may have. Sounds more/too progressive which is typical of these cheaper dampers a few of us run and from my experience, you must make a compromise as it will not have a good/decent setting @ both. I choose to optimize it at low speed piston speeds if the track is faster (for high MPH control), hoping it doesn't get too upset at bumps (high speed). Buttonwillow, for me, for example, and the opposite for a slower course-- Streets of Willow (which many just call an overgrown Auto-X course). On the street, I prioritize the high speed valving range since the roads around here are rather rough. Above all, give the suspension travel to do the best it can.

i think of shock / spring motion as a sine wave with frequencies and amplitudes.
compression, rebound, force, and time.

i hope i'm making sense here

magnetorheological damper , and we're done here.
