I went with 295s on 10.5" wide 18" diameter rims, 8.25" back spacing. Guessing at the suspension set-up, I went auto crossing for the first time this past weekend. No rubbing or anything with the 295s. 315's would be tight but I think I'll try them next!

You sound upset???
Your saying the fender lip area was more work to make fit than reworking the stock inner? I doubt that. But not here to argue.
The inner was designed to come out to the inside of the fender and drop straight down so you get the maximum space possible for compression travel under braking. The inner lip needs to be worked to provide more clearance with a 315 tire for sure but hey you don't have to widen the fender!!
sorry you were not happy with the product we have not had any other negative comments.

im sorry blake i would never recomend anyone buying anything from you before getting a waranty i fit properly before. if i buy something for alot of money , i expect it to fit . i have pics to show. but it would be better if you put up pics and explained what minor works means.

Here come the truth. Vendors build stuff. It all looks good till it meets the real world. For the cost of these parts they should fit. All about the dollar. Nothing about quality.

I'm not sure Blake reads this forum anymore, probably best to contact him directly.

Speedtech has a video up about their inner fenders.
I talked to Blake about them right when they came out for the extreme frame but ended up building my own.
