Yet another spring rate thread
#21
I've driven half way cross the country with 700/400 even with the wife in the car and I drive them regualarly on the street too. Revalved Koni sports with extended travel shock tops. I also have ISC sway bars. the car is suprisingly comfy on the street and you had better be a hell of a driver and bring some pretty dam good hardware to beat me on the track as well.

my problem is turn in right now. It feel very neutral and I can stomp the gas around corners, but, when i want to turn the wheel fast and induce oversteer for a quick u-turn or something it just plows. this could be partly due to my lack of an alignment, but without my rear bar I really lost the turn-in response.
when I had FM springs and no rear bar I didn't notice this as much, so I think bringing the FRC back down a little should solve it still without being tail happy in other situations.

I actually got to play on a skid pad with and without the rear bar on and the difference is significant.

Stock yellows, 450/300. Car handles great for such an inexpensive setup. I will eventually move to higher rates with r-comps, but this is a good compromise street/track setup if you want to just arrive & drive on street tires.

got my 450/300 springs and put it all together. I'm pleasantly surprised that the koni's at full soft, ride much smoother than stock. car feels neutral for The most part and a hair loose powering off the corner, although I'll be adding sways soon to dial that in and raise the FRC a bit. immediately increased my twisty road test track by 10mph, without an alignment. happy camper

There is no way that the Konis on full soft are properly damping those spring rates. Start experimenting with cranking them up and it should improve handling and ride quality. Find a road with some speed humps and hit them at 15-20 mph. If the car bounces more than 1 rebound event after coming down off the hump, it can use more damping. It's been a while since I did mine but I think I'm around 1.5 turns in the front and 1 in the back with those same spring rates.

That was just the first run. I have it at 2 turns front and 1-1/2 rear. I'm getting an alignment tomorrow and I'll do some more tinkering after that.
I'm running stock tophats in front and a 2-1/2" spring which doesn't exactly seat on the hat. Is everyone running spring isolators or is it not a problem?

I have mine at full soft with 400/250. If i increase rebound the ride quality gets worse. But it could be that they are 2011 years old now and leak at the adjusters and are just plain dead.

I have some older FCM shock mounts and I run an upper isolator from Energy Suspensions that's a generic application (# 9.6103G). There may be a tiny gap on the top side of the spring when the car is jacked up in the air and things are at max droop, but it doesn't matter because the suspension never droops enough during any kind of driving for the spring to be free enough to move around. I've checked the little paint marks I put on the perches, springs, etc and nothing has moved one iota since I had it corner balanced last year. It probably doesn't matter if you run without an isolator, aside from a little more NVH maybe.
