Rear end "float" on straight at lime rock

[jakell2010]

The shocks,,, LOOK new,,,it's an odd thing because it's a hard down hill right hand bend, when the car decompress' it feels like the rear floats,,,other than that it's perfect,,,tires are NITTO EXREME ZR-nt55 set at 28 f 36 r

The shocks are original, the issue is,,,I didn't want to any major money into the 99 986,, waiting for 09 Cayman S to come off lease and be in my $ range with LSD

A set of Bilestiens with alignment and corner balance are going to come in around $2500-$3000

Dude a full RoW 030 suspension(shocks,springs,front and rear sway bars and bushings) shouldn't cost you more then $1.2k from Sunset Imports. And installation for all those should be $400-550 max. $100-200 for an alignment.

Depends on labor rates, but at $110-120/hr the install is typically $800+

I would ensure that your spoiler is deploying and your spoiler warning light has not burned out. Manually select the spoiler up....I think if you do this with the car running it will stay up....and do a session

jaykay is correct about the manual deployment of the spoiler. Once you press that switch the spoiler will stay up until you either manually stow it or until the car is powered off and started again, at which point it resumes normal operation.
When you start the car, does the spoiler warning light come on and stay on until you start driving (like it's supposed to)? That'd tell you if the bulb burned out if you don't see it upon starting the car. This culprit is not very likely, but you never know, so check it out. Clearly the speeds you're getting to at this point should see the spoiler out doing its job, but unfortunately we can't see that from the driver's seat.

I do wonder about that GT3 nose...maybe it's providing more downforce on the front to the point where the downforce the stock rear spoiler puts down is no longer sufficient. Maybe you should see about getting an Aerokit-style permanent spoiler to put on the back, or if you don't want to drill your trunk lid (understandable), if you still have your original nose, maybe throw it back on and see if the car settles down?

I know Lime Rock Park's never really been one of the smoothest tracks out there, even after the repaving not long ago. Is the road surface where you're encountering this any sort of bumpy? It could be the line you're choosing has a spot that the chassis doesn't like, and gets that reaction from it.

is that section bumpy at all?

Ok,,this has been a real treat,,,first of all what's a ROW suspension,?,,,

Second, went to M- tech motorsports,,drove the car and put it up on the lift,,,appears that at one time (prior to me) the car was hit in the drivers rear,,,EVERYTHING,,,lower control arm track arm, and control arm link , Were bent and to put it simply the the wheel was crabbing,,,and caused the wheel bearing to go,,,,could literally wobble the wheel,

So ultimately the whole left rear suspension has to go and new needs to be put in

bTW,,we tried the spoiler up thing, and a different line on the track, what pushed me over the edge is when the wife and I took the car on a day trip, and it swayed so much that the wife got car sick

Thanks for all the replies and help,,,,what's the best way to go with suspension replacement ( shocks) or full coil overs , I ordered the hard parts from pelican
