I want to upgrade my suspension and I have no idea what to get. A few people mentioned linear spring rates for the track, that is about it. I have a 1991 MR2 turbo which I do a lot of road course track days with and put maybe 3,000 miles on the street with. I don't care if the ride is harsh or stiff as I am concerned with track performance. Here are some leads for used upgrades, but again, I don't know what is good to get.
Car Specs:
2950 lbs with me
~1300lbs front ~1600lbs rear
Currently Macpherson Stock Struts
"Product: Tein Super Street
Details: Great shape, height and damper adjustable, comes with front endlinks (needed cuz its shorter than stock). OEM strut mounts (one of the mount has some rust, has some water stuck on it for a short time at the shop), no leaks, no funny noise. Bolt it on and enjoy"
Front = 4 kg/mm
Rear = 8 kg/mm

I did not get a lot of info about these, but they are Ohlins and the ones on their site for other cars run from $2,500 and up. These have been on a drag MR2 before. Being sold by a Mr2 performance shop out in Tx.
Ohlin's supension set - Ohlins struts, these were 1) incredibly expensive when new, and 2) amazingly adjustable: 24 way or something. They are inverted style struts too. They have white progressive rate springs installed. The fronts have camber adjustable pillow ball mounts installed. TRD gymkhana race springs. These are amazing struts. $700 shipped.

Next are JIC FLT-TAR that have adjustable camber plates and 15 way adjustable compression and rebound settings. These have linear spring rates, I don't know what the rates are though. These are the most expensive on the site listed below for MR2 cars.
Used 15k still good condition.
Dirty in the pictures but you can clean it up.
No leaks, just decided to go with a more stock setup.
$850 shipped, 800 picked up. (located in san jose, ca)

Anyone have any input on these or another brand? Should I just get some Koni inserts and H&R springs?
