106 GTi
Rich - Imo it's the tyres, I ran avons on my valver years ago, awful things tbh. God knows what my mate had on his gti, it really was ace though.
I assume yours is 100% standard ?
They are bad but I have driven on worse - even when pushing hard they seem to have plenty of bite which is odd, I expected them to understeer on the front but they don't - only time they move around is under heavy braking at the back on uneven surfaces it likes to wag the tail a touch !!
When I drove a brand new GTi from new was P6000's which did the same ! They will be coming off anyway so not worried.
Car is not 100% standard - but at the moment suspension wise it is all standard for now.
