Changed suspension and brakes wheel sitting way out?

[wheat]

I have ride tech tru turn kit and c5 brakes from Tobin with his billet hubs the wheels are 17x7 with 4" backspace and have a 1/4 spacer to clear the calipers but now they stick so far out the fender is sitting on tire would need almost inch to clear any ideas?

[GoodysGotaCuda]

Looks like it probably needs 18s and more backspacing.

Man, I don't know about that. Any more backspace and the lugs are going to stick out further than the tire!

Looking closer, that does look to be the case. Those hubs seemed to have added a bunch of track width...

[csouth]

Not trying to be funny, but are you sure the backspacing on the wheels is 4"?

[killer69]

We would run a 8 with a 5" bs you are saying you have 4 - 1/4 so 3.75" no wonted it sticks out.
people seem to miss the fact that the Corvette brake caliper can cause clearance issues with MOST aftermarket wheels.

[Josh@Ridetech]

Hmm... The Tru-Turn keeps the factory track width. I've seen several guys run the combo that you are and haven't been pushed out near that far. Everything I can find on Kore3's site says that their brake kit only adds .200" of track width per side over a factory drum application. To me, it sounds like you might have the wrong hubs or the backspacing on the wheel isn't what you were told it was.

What is the alignment set at? Maybe it has positive camber in it making it look worse? Obviously like others stated, your new combination set the tire/wheel out farther, but the image is hard to determine what else is going on.

I think when the hubs and the spacers are combined you have decreased your backspace over an inch per side. This would be your problem....

Tobin's billet hubs actually narrow the wheel track, with disc spindles.

Q: Do the KORE3 big-brake kits change the track width from stock?

A: KORE3 big-brake kits are designed to minimize track width changes, however this varies by application as listed below. Rear track width changes increase by the difference in thickness between the OE drum/rotor and new rotor hat, typically +.15" to +.18" each side for drum applications.

KORE3 GM Short-Spindle Kit:
Drum (Chevy): +.20" [5mm] per side
Disc (Chevy): -.24" [6mm] per side

You're missing the text from the section for the hubs not the FAQ...

KORE3 billet hubs with a C5/C6 rotor in place increase track width .200" [5mm] per side over stock drum applications, making the overall track width .400" [10mm] wider than stock.

With that being said, those wheels don't have enough backspace.

[TheJDMan]

It is hard to tell from that tiny picture but it looks like the wheel hubs are way outboard of what I would expect to see. Any better pics you could post?

[wheat]

I put some shims in my upper control arms and it moved it in some

[wheat]

I checked backspace and its 4" rev wheels has info on their site they are cookie cutter wheels and its only backspace they offer in 17x7

[wheat]

Wheels are 17x7 with 4" bs how would going 8" with 5"bs change anything ? I bought these thing factory wheels were 7" with 4" backspace ?

[wheat]

Rear wheels cleared calipers with ease

[CliffsBlueCamaro]

Actually no; the 17x8 with 5" backspace wheel would be pushed out towards the fender the exact same distance as the 17x7 is now. They both have 4" of front space.

17x7 is really 8" wide. 8" - 4" BS = 4" FS
17x8 is really 9" wide. 9" - 5" BS = 4" FS

I am really baffled that you don't have ample space with the 17x7's even with the spacer.

What I posted above says the same thing, Chris, that using drum spindles will increase the wheel track .200 , per side. The OP's car has drum spindles, correct?
KORE3 GM Short-Spindle Kit: Drum (Chevy): +.20" [5mm] per side
Disc (Chevy): -.24" [6mm] per side

If his car had disc spindles, the wheel track would be narrowed .240+ per side and his wheels would work, fine.
Correct?

I'm wondering about that,too.

3.75” of backspacing is not enough. Your only solution is to get new wheels or add negative camber until they fit. No magic bullets here....

Looking at the fitment it would probably be better, but I doubt it would work even with drum spindles. He essentially took a wheel with 4" BS and made it even less with the spacer and the brake conversion.

Spindles are ridetech

Our spindles are a replacement for factory disc brake car, only a taller/drop spindle.
