I don't really tackle any viscous speed bumps, only ones I have to deal with are at work and they go all across the road so just lumps in the middle so no problems.
Had a few scrapes on the driver (is 70/60 really, 10mm lowering caps) but that was on 195/45/15 tyres. GTI is 205/50.
Sod it, if I can drum up the motivation to swap two cars of suspension, I'll do it!
