yes, i have had them on my car since august, last year

they are horrible for street use IMO.

I am switching to KW V3's next month.

KW V3 is the best street coilover.

KW seems to be the popular vote

Agreed, for 95% street use, and the person that does 1-2 track events a year. If you can live with a little firmer ride (but not harsh), and you plan on doing more track work with the car, I would suggest the TEIN Flex or TEIN Monoflex.

kw coilover plug
 

Shamless plugs deserve a discount! KW have a good rep.

We'll beat anyone's prices, and we have some of the most experienced technical people in the business....everything installed, tested, and given the Forge seal of approval. No questions shall go unanswered. :tup:

Penke coilovers for 370Z
 

I always had great luck with penke's. I'm not sure if the have a suspension spec fror the 370Z. Any infor?

Penske doesn't make anything in this range for the 370Z.

for best and most performance, do u need to purchase front and rear camber kits along with the coilvers?
thanks

Yes.:driving:

When people say 'Track'....are we talking about like Watkins Glen type of track or are we talking about auto cross track (hosted in large parking lots). I would like get some coilovers primarily for steet use but I also auto cross (6-8) times a year. Would I be good with the V3's or BC's??

Go with BC's! :tup:

How competitive are you looking to be with AutoX? I would lean towards TEIN for this.

Tein > BC on performance. But Tein < BC on cost.
So the better one might be clear, but I'm still not sure the extra money is justified for a couple of track runs.

Sharif, if the question would be best bang fo buck. What would your opinion be?

my understanding and talking to the vendors is:
Tracking on road courses and autox-Tein mono's
Autox and street- Tein/KW V3
Steet-KW V3

And for that reason I'm planning a soon purchase of the Mono Flex's
