Thanks mate! š but we will build a NA engine, not a turbo.
So, some of the first mods, were front subframe bushings - we were changed them on solid aluminum ones.
subframe also was sandblasted and powder coated in gloss black.
front arms, rear axle and and front anti roll bar got powerflex black series bushes.
we were buying ST XTA coilovers kit (astra mk5 vxr) - which fits with some small modifications. front turret holes needs to be increased in diameter slightly.
but not all going so smooth - on st springs, rear end sits really high (may be lightweighting gives those result), so we've bought shorter eibach ers linear springs (60nm) with helpers, and make new spacer rings, to fit springs correct between body and axle..
to get maximum space for wider tyres on front, we also changed front springs on shorter ones (eibach ers 70nm, 140mm length). so after that coilover's lower nut stays higher then tyres, even on good lowering.
our main target from the beginning was to fit 245 wide wheels (max allowed in our timeattack class) on good lowering without any rubbing, scratching etc.
rear arches were rolled, on the front - only arch liners were cut in connection line with wings (and new fitting holes made)
st xta colovers has oval holes on lower mounts and eccentric top mounts, so with max camber setting on the top we've get a lot space for our wheels.
