hey folks ive been having some wibble / wobbles at high speed >90
(this was when i was at knockhill a while back)

now i have an 03 sti with k sport 356mm 8 pots on the front with o.e - 2 pots rears

it happens when im not braking and it also happens when i am

dont think it happened when i had my 4 pots

could this be a geo problem or possibly a brake bias problem

i do also run a very aggressive offset (could this be a contributing factor)

cheers in advance

 

Does that not rule out the brakes then

 

It could be a disc ballance problem , if you have just fitted the brakes and now it does it , it sounds like it could be related

 

how are you getting your aggressive offset ? if with spacers it could be the cause

 

I would have the wheels balanced and the car aligned.

 

You will have gone a bus ride away from the "factory settings" if you have altered the offset significantly... Thus the effect of variations in tyre grip will have a greater turning moment about the centre of the car...

Or your wheel bearinga are shot ?

P.S. What offset, spacers used, who fitted the brakes ?

 

no no spacers needed they are rota g forces

with an et38 offset so they stick quite a bit out

ill get the brakes looked at and see about a laser allignment

cheers

how can this be fixed, would the brakes have to come off

russell (aka wuz) top bloke knows his stuff

if the bearing were shot would i hear any form of grinding noises etc

cheers

Not at the very first instance, the offset will exaggerate things tho'...

cool cheers mate

ive got two sets of alloys (rota's - road / pff7's - track)

would it make a difference if i got a geo set up with my rota's on
and then swapped to my pff7's for the track days

cheers

steve

 

Geo won't change, but if the offset is very large, you may need advice on the best set-up and decide on road or track, or somewhere in the middle, IMHO.
