I'm currently assembling my 309 beam and I've been rummaging through boxes of beam parts and found 2 pairs of front mounts at which point I noticed the stud offset was different between the two.     Did a bit of research and learnt that the 1.9 GTi has offset studs - that'll be the top pair.   The bottom pair will be the 309 ones.   I read that a possible reason that the 1.9 having the offset studs was to bring the beam further away to allow for the larger rolling radius of the tyres. Sounds plausible anyway.   There's not a great deal in it, but which pair would people advise I used? I'm fitting VTS arms and will be using 195/50/15 tyres.   My 1.9 axle currently fitted does sit quite a way back - not very far at all from the valance in fact.
