I couldn't pass up the Xmas sale at Z1 lol. Got it for less than a grand. The OEM suspension all though not terrible by any means(for OEM it is quite good). Man it is way too bouncy. Scares the heck out of me at BRP from grapevine through club corner, and I feel I really limit myself at AAA and Big willow through the fastest parts, because once things start shaking, I back off. BRP the car hardly ever gets planted it seems with all the camber and elevation changes. Definitely need some faster springs as well.

Agree. Stock wants to bounce over little bumps and then "float" to the outside. Very scary! Can't wait to finish and get this bitch planted!

The coilover is not worth it. Save your 2k and get camber arms and sway

Even with stock vlsd, still manage fast laps, yes the diff is huge. Tires for us not so much in SoCal we run rs3 mostly and a few on Td's we don't run Hoosiers like NorCal or other areas.

Here are my rear spring dimensions that was asked prior 8"x2.25"x 450lbs

Doran said he hits 300* diff temps within 3 laps. Say the OEM VLSD never hit 250*. Is it possible it won't become sh*t from over heating? Just finished my diff cooler and can get the temp to drop 40*.

You will max out stock suspension fairly easily, took me about 5-7 track days to max out the car easily on stock shocks/springs and front and rear camber arms only w rs3 tires. Next was coilovers, diff, sway bar and dropped a lot of time there.

Right now it's lack of track suspension alignment=no front or rear camber arms

my Tein monoflex are 783 front and rear. Both Mike Skeen and Brian Kleeman loved the way my car handles when they drove it.

Glad to hear. My car is going in tomorrow to have the Tein Monoflex installed (with EDFC Active) and a bunch of SPL goodies. Looking forward to the start of the track season!

That has to be a real coilover in the rear at that size?

martin82 · 12-27-2013, 04:44 PM

that's correct, its on my JRZ RS pro, I didn't install the rear springs yet

Mike on a scale of 1-10 1 being "perfectly drivable on street", 10 being "absolutely no f-ing way am I driving this thing to work". How would you rate your car for daily driver use, based on just the springs and ride quality-ignore everything else.

As a Mike also, 9.5. No radio, AC, delrin bushings, etc...

...there is a reason my car has no tags.

mine also. I don't remember the last time I drove it on the street, as its been over two years, but I do remember it wasn't bad at all.

interesting input in this tread :P

Took mine off the street also. The aggressive alignment I'll be running is track only. Car is being setup up for the best turn in possible. I'm going full out.
