Just changed my wheels from B5 RS4 reps 8" x 18" to BBS CH's 8.5" x 18"

Both fitted with 225/40's

Original wheels 24KG, new wheels.... 20KG!

That's a saving of 4KG per wheel and tyre. 20KG less to lug around including the spare. Original rep wheels 20% heavier!

Car feels SO much better now... Me Happy

Bloody hell Mark. I need to get me some wheels

BTW: go for a light upgrade brake kit as well

That's where I loose, B5 RS4 brakes ain't lightweight, though I've heard the B7 kit isn't light either.

Dave, can you stick one of your many standard 17's on the bathroom scales, be interested to hear what they weigh?

Mark from what i remember when i was weighing my standard 17" wheel with new tyre was 22.5 kg and my 19" RS6 rep with 235/35 new tyre was 25kg

You can honestly tell the difference from such a small saving? Is that not the same saving as having a fat passenger compared to the girlfriend?!?!?!?

Dave

Its to do with your unsprung weight and rotational mass. Reduce this and the car will feel a lot lighter on is feet.

Chuck two bags of coal in the boot you will probably not notice the difference.

That's exactly it. It has made a big difference

I'll be looking out for a pair off those calipers me thinks. Will fit a treat over my discs
