Same wheel clearance wheel to strut - 18 x 8.75 Xxr 35et approx 2mm.
Bora/R32 shocks are an interference fit into the hub assembly with a locating tab that slides into the split housing where the single use bolt clamps the whole thing together. No threaded housing as in most other coil over conversions.
The bottom spring platform dictates the overall ride height and the effective spring tension is static and not adjustable.
On my WRX the strut threads into the hub and that controls ride height. The spring rate can be changed by adjusting the bottom spring platform independently, allowing a percentage change in spring rate.
Ive had my coil overs checked and adjusted on a shock dyno and I use 12kg front coils which were also matched once I’d arrived at my chosen ride height ....
vw don’t make it easy !!!
