High Speed Vibrations

[33driver]

hey guys

well i've been driving the R33 for a week and a bit now and all seems pretty sweet. There are a few things though that I'm looking into. I'm experiencing a vibration at exactly 100km/h and above (worse at 100ks)

It feels like the shudder is coming through the pedals, however its more through the suspension and geometry of the car. Its not brake or steering shudder as I know what they feel like.

The suspension is VERY hard and i'll be replacing it with new coilovers shortly, however this sort of feels like its more in the pivoting sections of the suspension geometry, morel iek a tie rod or something?

Any ideas on where to look?

Thanks guys,

matt

check your bushes (i.e. lower control arms, castor bushes) also check your tie rod ends, and the rack ends...

GET A WHEEL BALANCE

haha, i thought that too, but he said he knows what that feels like so i thought that would have been checked already

good thinking, he said the wheels were done when i bought it but they came off a different car so I suspect they weren't properly done, i'll have a wheel alignment and balance done just in case. the one thing i have never expereinced is imbalanced wheels since i've always had mine done so that may be it.

would be that i'd say. when i first got my new rims they were balanced pretty shitty, real bad vibrations at 100 n over. wheel balance... which was like 8 bucks.. and was all good

ye wheel balance definately, best two on front. and if they are new wheels(new to you), then get the place to check they dont have any damage, sometime you can balance the wheel out perfectly but if the rim is buckled its still no use.
