Installed the D2 coilvers to my car yesterday...
Installation was very straight forward, and the back ones took no more than 15 min each side! I will post up pics tonight..
Had the car sitting pretty low on stock rims, but enough to still just clear drive ways and speed humps.
Took the car for a drive... nice... then i got up to 55-70ish Kmh then there is this HUGE ass end vibration that you could feel all the way through the car..
It worse when i put the power down (accelerate hard) around the 5-6rpm mark, then when i am at high speeds and lower rpm its not there!

My mate thinks there is too much camber in the rear wheels.. ( worked out roughly 1.8neg) so i raised the car almost back up to stock height.. The feeling was still there but not as bad..

I'm worried! I think it could be the CVs, As I'm also hearing a very small and sharp clank sound when i take off slowly or turn slowly..

Any help please??

Here are the pics!

Take it straight to a suspension specialist!!

That type of problem can be dangerous and you are gonna need it by Sat Night!!

It could well be CV's if your car has some mileage on it.

I've noticed some tuners put approx 1/2 inch spacers between the diff output flanges and inner CV's when lowering the car. My thoughts was they did this so the CV's rollers ran on a different part of the housing surface.

When a CV joint wears the rollers or balls wear a trench in the outer housing. If you change the geometry slightly the rollers are positioned to the side of the trench, and under power get pulled back into the trench with a loud click.

Alternatively, try swapping the inner CV's side to side so they run on a different surface.

If you have changed the camber lots it could also be rear toe. Most cars suspension tends to toe in on squat. You could have a truckload of toe in causing the tyres to twist outwards till it trips over its own tread.

I'm going to swap the CV's tonight... hopefully that does the trick...

i had the same problem as you. But mine was due to me forgetting to tighten the lug nuts

also, a friend who works for honda told me that if the rear end is too low then it would do some damage to the diff due to the way the rear end was designed.

LOL i made sure i tighten the nuts.. been down that path b4!

Was going to do it last night, but realised that i didn't have and boot clamps.
Tonight if im not tired ill get it done.. need it for the weekend..

hope it all works all dbzerk. I find that my D2s are very stiff! its insane driving them on parramatta road...

btw how low was the car? off the ground??

dbzerk

When i first installed them the front air diffuser was less than 4 cm off the ground..

u mean those lil mud flap things? i took them off cus they were scraping along....will it affect anything? i measured the car today and its roughly about 9-10cm off the ground. raised the front up abit today cus it was too low lol
