So what are we all doing in terms of ride height for track days?
measuring from centre of hub to fender...
I've previously had my coilovers set to -
Front 345mm / 13 5/8"
Rear 355mm / almost 14"

That's with a Whiteline roll centre kit, stock arms etc etc.

So what do people think is optimal for handling (i don't care what it looks like), for setups with and without the RCK installed?
Most non-RCK setups down here seem to be around 350mm(13 3/4") front and 355mm (14") rear.

Keen to see what some of the clever people think

PS mods please move this to Suspension section if it's better off there..

I thought this would be dependent on spring rates, valving and shock travel. No?

To some extent yes, of course it does
but there must be an optimal starting geometry for both scenarios? (with and without RCK). where the roll centre is in the best position... an average sort of thing?

I typed up a whole response, but deleted it. I doubt there's anything I can type here which you don't already know. I still say a proper suspension setup specializing shop is your best bet, preferable one that works on evos.

^ agreed.. I'm getting the alignment etc done professionally this weekend
I'm looking to set up the ride height before i go, then i can fine tune after a few track days.

after my engine swap, the front is sitting much higher than it was previously (like an inch!) and the rear is 1/4" higher. I took a little weight out of the car, but not that much. I'd best check the springs are seated properly etc.

Curious to find out optimal ride height too ... Sub'd

This thread needs some help.

I'm doing coilovers and need to decide what the ride height should be. Going to 265/35-18 tires will lower the car 5mm (0.2 inches) with no change to geometry. I don't want to lower the car more than one inch total, or about 20mm more. Lowering 1/2 inch total is about 7.7 mm. So I'm guessing that I would lower the car somewhere between 7.7mm (0.30 inches) to 20mm (0.787 inches).

For reference: A quick measurement of a completely stock MR leads to: stock fender height above the axle centerline is ~15 7/8 F and ~ 14 7/8" R.
