WIDENING THE STOCK WHEELS

The rear stockers look great up front. I think you're right about moving the rears out a little. I went 20mm just so I wouldn't have to cut the threads on the studs, but 15mm would probably look better.

How do you like that Whipple so far?

The Whipple is good. Still needs more power though. Had to stop racing at the LS Fest due to a leak at the oil cooler. The drag radials were too new to hook very well.

Ok kmcd,
I have read the entire thread but kept getting interrupted at work so I just want to do a short summery. You widened the rears to 10.5 and are running a 305 tire correct? Also you had to adjust the break cable and lines not to rub? The rear spacers are for looks and not necessary?
The reason I ask is because I want to do this for running at the track. I think like my last girlfriend, the extra inch and a half makes a huge difference lol. But I am not really into putting in spacers and cutting the lug bolts if I don’t have to.
Also just an FYI I had JDP Motorsports install Pfadt sub-frame bushings and rear arm package. This helped with wheel hop and gave me 2 – 3 10ths on the stock PZeros. The rear end “plants” a lot better. But I would like to run the 555R or the M/T 3727R.
Your thoughts please and thanks.
Also I did buy a couple months ago a complete set of stock wheels and tires (brand new) for $1,000. So I do have donor wheels.

jonnyb!!!!

You will have to run spacers if you widen the wheels. We have a car with the rears widened and the lugs did not need to be cut. I can get you any information you need. Talk to you soon!

My rears are widened to 10.5" with 315's. No spacer. I did get some rubbing while I was autocrossing. No issues on the street.

Ok so I should be getting my wheels back from Vaughn tomorrow or on monday. I ended up going with widening the fronts to save some $$ and less hassle right now. They are powdercoated black and I got the fronts widened to 10.75 . So I need a 20mm spacer for the rears and what size spacer for the fronts (since I'm moving the rears to the front). I want to have an aggressive stance where the wheel is almost flush with the fender lip. Are the H&R's the best spacers? Do I need to do anything else other than that? I guess I'm gonna have to get my center caps painted black to match since they couldn't powdercoat them.

[yotaman96]

No spacer needed to put the rears on the front.

Sorry,

I haven't looked at this thread for a while. I'm running 315s on the back, not 305s. Like yotaman96, I did get some rubbing at the track, but it wasn't enough to be a concern. Now I'm running 20mm Eibach spacers all around, but they're mainly for aesthetics. I suspect that if you run 305s, you won't have any rubbing issues at all.

[STARSKI]

So no need for spacers on the front if i stick the rears on the front. And a 20mm spacer on the rear? What tires should I get for street? I'm thinking a 305? Are the H&R spacers good? Do i need to cut the lugs too?

[BVaughan77]

Has anyone widened the rear wheels from the outside of the wheels (meaning an increased offset or deep dish look)? So far, I have seen two threads of people widening the stock wheels on the inside. Thanks!

Look at your wheels; there is no front lip to widen.

ps...i have stock 20's for slae ...sorry, dont mean to thread jack

Ok I need some help! I got my fronts widened from Eric Vaughn to 10.75 and today I went to a local wheel shop and it was a disaster. I was trying to get the do the fitment with spacers etc and things just didn't quite work out as planned. Anybody know anyone I can take it to in the Bay Area to get the spacers etc done? They were saying I'd need like a 47mm wheel adapter to get it to clear. I was under the impression I could use a 20mm hubcentric spacer?

[yotaman96]

Since you widened the fronts and they have a different offset than the rears, I believe you need a 1" spacer. You will also need to modify the emergency brake cable routing.

Are you putting them on the rear? if so the 20mm should work. I have 25mm on the rear of mine with 11" widened wheels.

[STARSKI]

Damn conflicting info here haha! So you have 25mm adapters on 11" widened fronts? I have 10 3/4 widened wheels. So you're saying 20mm? Should I call ADM or?

25mm is almost an inch. If you look back at threads he started, he says his wheels were widened to 10.8".

[STARSKI]

Ok cool so I talked to ADM and they have the spacers I need. Gonna order them today. Should I stick with the Pirelli P-Zero's? They're expensive but seems weird to have 2 different sets of tires if I get something else.

How many miles on your Pirellis? The INVO is a better performance tire, and it might be worth replacing all four.

By the way, I'm running 20mm hubcentrics (rear stockers widened to 10.5" / 315 INVOs), and have plenty of clearance.

Only about 6k on the tires.

[yotaman96]

FYI, since moving the rear wheels and tires to the front, I have had some rubbing. I never felt it rub, so I'm guessing it happened while autocrossing.

If i put a spacer to put the wheels flush with the fenders will this eliminate the rubbing on the inside tho?

I'm thinking of adding a small spacer. It shouldn't be an issue unless you drive aggressively. I also have Pfadt lowering springs.

I was thinking of adding a spacer just so they sat super flush with the fender, how do they look up front without a spacer?

I don't know if this helps, but here are the front stockers (20x8 / 245s) moved out 20mm. Yotaman's pictures show the rear stockers (20x9 / 275s) up front with no spacers.

We're both running rear stockers (widened to 10.5 / 315s) on the back. I'm running mine with 20mm spacers. His are flush on the hub. The 20mm spacers bring all four corners to just about flush with the fenders on my setup, but his fronts are an inch wider and are more concave because of the slight difference in offset between the front and rear stockers.

Clear as mud, isn't it?
