It appears the lowest factory wheel offset offered on a Factory JCW was +48, which means the lowest offset wheel you could use in C stock would be a +42 (Based on the .25" rule). Were there any other factory wheels available that were +45 or +42? For a 17x7? I was thinking of going with some Konig Feathers, but I think their +40 offset is illegal in C stock.

 

Unfortunately, 48mm offset is the only offset offered. The RPF1 isn't a bad price at $225/each from Tire Rack, and, they weigh in around 14.5lbs each with a 43mm offset.

 

Thanks, yes, I scoured for something else, but alas, +48 it is. I went with the TD PRo Race 1.2's, although I was close to getting the RPF01s. I had RPF01's on my STI and wanted to try something different. Thanks for looking

 

OasisT:
Thoughts on the Kosei K1 TS.
Shows to weigh in at 15.0 lbs with 42mm offset.
$29 less per wheel than the silver Enkei RPF1 and looks like ~ ¼ lb heavier.

 

Those are a quality wheel, I had a set in the past. I don't think anyone is going to really feel any difference between the RPF1 and K1-TS to be honest....

One thing I thought about doing is running a 42-43mm up front and a 48mm in back to help with rotation(might help some) as well as narrowing the rear track. Only issue is, I don't know of any lightweight 48mm wheels(although, haven't really researched much more than a quick look). It would be a fun thing to try out since everything else has been done to my Mini. I'll post here if I can find a 48mm lightweight wheel and actually do it.

 

Me neither...
If I were THAT concerned about weight, I’d skip the cheeseburger and fries at Five Guys for dinner later this week
Thoughts on tires?
I was an active SOLO participant from the mid 80’s to mid 90’s and then went road racing.
Am looking to play at SOLO again.

Thanks.

 

I've been running in a street tire c-stock class on Dunlop Direzza Star Specs in a 215-40-17 and performing very well. I haven't run on race rubber since I had my STI, so I can't make a good recommendation there.
