Hi MattKab
I have been asking questions regarding rear suspension, and spoke to a few people with knowledge. Hopefully some of it now makes sense.
If you add Avo Adjustable Coil Overs this should help the torsion bars out to take some of the load. They are fully adjustable, so you can adjust them to suit your needs,
www.vwspeedshop.co.uk sell them, give Paul a ring.
Low Profiles do spin more than higher profiles, I think this is also due to the fact that the higher profiles twist and absorb some of the power allowing hookup, as you say the "snatch" effect. Probably going to get a set of 15 inch Ercos with street legal slicks with I will use for the strip, and keep the Cups and low profiles for street use.
