RT 615's on Stock 05 BBS

wrxridah · 01-22-2008, 04:16 PM

Will Falkin RT 615's, size 245/45/17, stock 05 BBS, clear with Prodrive springs and negative 1.5 Camber in the rear? Just looking to get some affordable new wider track tires to replace my RE070's. Or would you recommend getting another set of stock size Potenza's? Thanks.

I have the same size and I am running Cobb springs. I have around the same neg. camber in the rear and have had no rubbing during auto-x's

Shouldn't be a problem.

**T3h_Clap** · 01-22-2008, 06:51 PM

they are taller than stock, but with your setup and the stock BBS's you shouldn't have issues.

a 245/40/17 is a better setup.

pharo · 01-22-2008, 07:29 PM

the only reason I would see 245/45/17 better than the 245/40, would be that the taller tire allow you to gain some mph in autox. I am not sure how much of a benefit it would give, but I know I find myself debating whether to shift or not a lot.

**T3h_Clap** · 01-22-2008, 07:43 PM

that is true.

Downside is the setup may or may not work with all suspensions.

Thanks guys for the replies. 615's don't come in 245/40/17 unfortunetaly. 245/45 it is.

I've read that 255/40 are the closest to stock diameter and have been run successfully by several.... Gonna run that set-up in a few months when my tires go out...

wrxridah · 01-23-2008, 12:09 AM

Anyone know about 255/40/17 with Prodrives?

Kickstand · 01-23-2008, 04:15 AM

they work with swifts for sure, and they are lower than prodrives. I just had mine installed monday, they feel great. A little mushy on turn in, but lots of grip.

wrxridah · 01-23-2008, 09:04 AM

Is it "mushy" because the SideWall isn't as tough as stock?

STI_Mike · 01-23-2008, 09:09 AM

i thought the only size they came in was 225 i tried to get 235 but i was told they didn't make them in that size.

It comes in both sizes plus many others... please check with the Manufacturer or a (reputable) Vendor before you start to spread misinformation.

the "right" sizes for an STi in the terms of RT615s

225/45/17
255/40/17 (may not fit depending on offset/width/suspension)
235/40/18
265/35/18 (may not fit depending on offset/width/suspension)

Will 255/40/17 fit on the stock 17x8's?
