Nice stance Kev...looks pretty similar to the Megan stance. Are you getting any noise/chatter from the rear spring due to the lack of lower rubber seat? Thats what I would be most concerned with.

A few degrees will make a lot of difference. Can you tell me what you were able to get to?

No, It was a shop on Ebay. Best price at the time!

I know you said PM you but I got the rear kit from VIP Status along with the wheels. I can't make up my mind on the rest of the kit I'm going to use.
My wheel offsets are +10 rear & +15 front.

Zero noise!! Very solid feel!! No more of that stiff twist you feel with the Megans. Day three and the ride is getting better. Remember the difference is in mm if left in.

True!! Here are the final specs. Notice the front camber slightly off. The left rear was tough also. One adjustment dominoes all the other adjustments. Like chasing your tail. I'm not sure if it's due to using Ichiba links instead of the SPL. All is close enough for me though.

Interesting. At least they got the total toe within spec (little effect on steering and some crazy wear). Now, the front camber looks unchanged - this car doesn't have fixed bolts does it? Can it be changed? I am surprised there was no change at all.

You'd need the adjustable control arms to get it right on the OE spec.

you don't want their stuff. GTE in Atlanta is a very reputable alignment shop where most of the racers go and they told me to run, not walk from their products. Eibach has some, but as noted elsewhere, they are made by SPC, which to me means, they must be ok for eibach to rebadge them. I prefer SPL parts though, myself.

Thanks for the info!! I'm still learning about these cars and available quality products!

wish I'd realized your were ATL,, would have like to gone for a ride with the Megans just to see how they are.

Kev > not to stray too off topic but when you installed the Megans did you set any preload on the rear (not sure if this can be set on front too?). When you reached under the car and grabbed the rear spring could you rattle it or was it solid? How about with the rear jacked up? I can rattle the crap out of mine which leads me to believe the installer set zero preload = noisy rear springs.

you need to preload the rears so the springs don't move when the tires are off the ground. You can't and don't need to preload the front.

You cant and dont need to preload the fronts because the Megan coilovers dont offer this adjustment/feature or is that with any coilovers for the 370?

azn370z · 04-06-2010, 06:36 PM

You're not supposed to adjust the springs on the fronts. You use the shock to adjust height.

You have to use the rear springs to adjust height. Then you shorten the length of the shocks to add preload.

jmlenz · 04-06-2010, 06:47 PM

Azn370 > got it thanks. So you have the proper amount of preload set and your still getting clunks from the rear huh? Thats a bummer. Im hoping my noises go away after adding preload.
