My cabby shhhaaaakkkkeeesssssss

Well My cabby has been shaking very much lately, it happens as soon I cross over 80km/h to 100km/h, but sometimes it's between 80 and 90 and sometimes 90-100 and somtime he doesn't shake at all! and is shakes form left to right starting at the end of the car and when I go faster the whole care shakes, but as soon I go over 100 it stops and the car goes normal again

I have brand new suspension from hottuning

what the hell is wrong with my car??? He's starting to freak me out

A few things, engine mounts, top strut mounts & Tracking and balancing out.
When you fittd new suspenion, did you have tracking, camber done? if not i'd say this is likely cause as it would also knock balancing out on the tyres
Pete

yeah I took the car to a tracking the day after I fitted the suspension. the wheels are perfectly balanced !!

do you have non std or aftermarket wheels fitted??

do they sit tight onto the hubs??

if not you need spigot rings to make them fit snug onto the hubs. this will centre the wheel and you should see the vibration go.

nobb they fitt perfectly, ats cup that came under of Mk1 GTi

Main question, as this happened since the suspension fitting?
Did you fit the suspension yourself?
Are all the parts in what you mention as suspenion, NEW, i.e. inc top strut mounts, shockers, springs, bushes, even new bushes on wishbones or new wishbones, steering rod arm/ends, all these will play a major factor in how the car responds.
This should be a main purchase buy in my eyes when you first buy an old car, change the lot, will come to approx ?400 for everything brake, steering, suspension related, but then you don't have the worry and many years of happy motoring
Did you buy the parts yourself or did a company buy them, do you know what brand name they are, are they a quality item, reason i ask this is even thou i have bought brand new parts in the past, one in question, Febi top mounts, they failed on 1st day, which gave me vibs in car as basically the strut leg was slighty moving.
If a company fitted this lot and you had this problem since then i would go back and mention problem and see if they can rectify it for you.
Pete :wink:

orginal top mounts and bushes

New wishbones (both) and complete new bush set for the wishbones.

There is new suspension, shocks and springs.

I fitted it my self… I done this very often because of my job so this is not new for me

I don't know how the car was before since I bought it not running, and I only have been driving it for 2 months

today was a good day, he didn't shake at all, but I think it will start again tomorrow
