Looking for some feedback on how big a difference wheel weight makes in terms of feel/acceleration on the MCS....specifically is a ~5 lb (20 lbs vs. 15 lbs) difference per wheel enough to be noticible?

Thanks

 

Check out this LINK

My feeling is 1 lbs. of unsprung weight loss= 5lbs. of regular weight loss, this reference says 10 lbs.

Needless to say the best weight to lose is unsprung weight.

I lost around 14-15 lbs unsprung weight per corner with my wheel setup and the difference is huge. However, like any change you tend to get used to it and forget how significant it really was.

 

Does that site take into account unsprung rotational weight?

I think the rule of thumb for that is 1lb of normal weight = 10lbs of unsprung rotational weight.

 

Cool, thanks. Hey how are your Roto's holding up-no problems? It's one of the rims I'm looking at.....do they come w/ hub caps? (every pic. I see of them has no caps

 

The Rotas are holding up just fine! I have driven them very hard through the twisty mountain turns and they do great. I will be autocrossing them in a month or so.

Here is a very dirty shot with the hub caps on:
