Car still rides on standard suspension (first one for me in decades as I've always gone the whole hog as regards mods with low coils, Koni shocks, etc), but the insurance companies gave me a hard time about the wheels and stipulated "no more mods would be accepted".
Also, my driveway is not that user friendly and most of my cars bottom out (I had to resort to ramps to get in the garage with my MR2!!) so best just to leave as is for the moment.
Interesting point with the wheels is that the front tyre/rim combo is 0.5kg lighter than the standard 17" setup and the rear is just 0.5kg heavier than standard which gives an indication as to how light the rims are despite their size. Certainly helps unsprung weight.

ps You get some great body kits, but simply, they are not for me. I love the original design.
