Sweet!!! I had not seen those yet.....thanks! I may be in contact with seller.


Anyone have input on whether jumping up from a 18x9.5 using 275 wide A6/R6 or R1s to a 18x10.5 setup would be worth the investment if I stick with 275 wide?


How about if I roll/pull rear fenders to possibly allow use of 285? Keep in mind this would be for wheel to wheel road race events with 30 minute races.

I wouldn't risk a 10.5 without having the RT links as a backup or at least a 8+mm spacer in the rear. On Eneki 18.9.5's and 275 Hoho's I have about 3/4 of a big finger, with 265 R1's on 10's I have barely 1mm and didn't rub. Unless you find a perfect offset, build a custom wheel, get RT links, or cut the fenders and run your own over-fenders it's not worth the hassle in my opinion. In my races everything else is a big block so the ~20hp hit I get for going to 285's isn't worth it yet.

Thanks for the feedback, sounds like all the extra work and cost starts to really add up.
I wonder how much of a gain one could expect to see in overall grip from the wider setup?

Depends on the track and setup really. The width offers more "time" with the tire at peak conditions. So if your 3500lbs, have a 60min race, and slide all over then i'd opt for the widest possible. However if your 2500lbs, a 10min race, and don't slide then the narrow options work. Basically you have to take HOT tire temps and pressures to see what is going on to determine more or less rubber. Also consider MPG/MPH loss/gain as more rubber takes more energy(power) to push but also absorbs more energy(temp) in return.
