The non concave face is what makes the wheels fit. probably not going to matter what wheel you get lol If you want a concave wheel up front to fit with a BBK then your going to be looking at wider then stock fenders, and the 10mm DF fenders wont cut it for most options. You can gain 15mm useable area just by pulling the stock fenders. A 9 +45 with an additional 20mm to clear the Stoptechs puts you in 35-40mm J's racing fender territory. I actually prefer the looks of a concave rear with a convex front on a RWD car. A non stag concave set up on this car makes the front wheels stick out and big/awkward looking to me typically. This isn't a AWD Subaru. But that's just my visual preference. Obviously there is a fitment factor here that has to work first and foremost.

I thought downforce are 30mm? Wouldn't that be plenty if I added a decent amount of camber. And yeah I just have someone offering me a fair amount for the stock fenders so I rather just get wider fenders

 

Concave rpf1 and bbk do not fit on this car even with +30 downforce fenders. Not even close. You must run convex rpf1 if you want bbk.

Correct, my mistake. Still wont fit with an effective 9 +25 offset. Your going to need J's fenders or something else that is 40mm wider then stock. Then you have to figure out what your going to do for the rear so your not increasing the front track width 80mm alone. Or you could just get a convex wheel with a proper offset. Or shop for an expensive custom offset multi piece wheel.

 

Your best bet is to buy a different set of wheels. I am fairly sure that there are options in the 17x9 +45 size that also fit BBK's. Hell my 5Zigen FN01r-C's in 17x9 +43 fit over my brembo's and would fit over stoptechs as well. Sell your RPF1's as a set and look for different wheels.

 

A guy offered me a trade for the 17x9.5 +38 rpf1's. I know those still arent great but do you know if they fit any better?

 

No, those wont fit your BBK nor your front fenders.

 

Let's see they have the same face so no they won't. You have already rejected the style of rpf1 that has bbk fitment. So either A buy new wheels or B spend thousands on body parts, paint, cut up your car, run stupid spacers, and stay with the same wheel or C don't buy a BBK. Selling a set of 17x9 +45 rpf1's should be pretty easy so long as they aren't damaged or in otherwise bad shape. Look through the stop tech thread and find a wheel with similar or the same specs and buy those.

 

Yes, just sell them. Even if you have to drop your price a couple hundred its cheaper than new fenders.

 

Well that sucks! I was just thinking that next years tax refund would go towards BBK, but I used this years tax refund on the RPF1's. The only other wheel I would consider are the Advan RG-D's. Will those work with BBK?

 

Why don't you do some research before buying parts?
