Offset Issue? with new Brakes

I Installed Wilwood Disc Brake kit in front, I just tried to move the car yesterday and found that my tires are touching fender corner now, kit states it will move offset +.19 I have 235 70R 15 Cragars with 4.00 Backspace with 0 offset how can I resolve this issue? also put on the Wilwood Spacers, should I remove the Spacers, at this point leaving today and will not be back until July 7th, so any suggestions I will try when I get back home

Re: Offset Issue? with new Brakes

I am running Kore3 Hubs and I believe they moved the front track out about 0.25" as well. I have 15x7 with 3.75" BS with 235/60R15s and no issues rubbing fenders. I must run a 0.25" spacer to clear my brakes though.

I also bought some 15x8 4" BS wheels and they seem to clear as well.

I have a 71 Chevelle, what do you have?

If your wheel spokes will clear the calipers, remove the .200 spacers if not needed.
Is your car lowered? If so, post a photo of its ride height.
27" tall front tires and a lowered ride height sometimes don't go well, together.

Re: Offset Issue? with new Brakes

I will take them off, when I initially checked they did clear the calipers but wanted to make sure since I had already purchased the spacers, car has new springs all around stock height springs, I will take photo next week once I am home again, traveling again for work now, Boy do I miss my Car!

Re: Offset Issue? with new Brakes

Okay removed the spacers still touch corner of fender when turn wheel, as Wilwood kit moved the offset to .19 how can I compensate for this I see Cragar has a 15x6 with -3 offset and no I do not want to roll or push my fender out, if buying new rims for the front or tires then if it will work i am open to that, also I was thinking maybe raising front will do the trick with spacer in the springs, I do have big Block springs that I am holding for my eventual engine change, which I probably wont do until next year spring as I am planning on buying another house first for investment, have to compromise with the spouse.

Re: Offset Issue? with new Brakes

I'd say new wheels would be the "correct" way to do it, but that could be expensive...

IIRC, there may be some "narrow" control arms, but that's expensive too...

New brakes that don't have the increased tack-width issues?

Raising the car up might work, but may also cause problems if you hit a dip, etc...

Once you go RAT, you never go back...

Hi, "Rex" - I don't know why you jack up the size and boldness of the fonts in your posts - unlike most everybody else here - but I hereupon ask you to stop.

It is distracting - not to mention disconcerting when one scrolls down from a regular fonted post to one of yours.

Thanks for your cooperation.

Is it necessary to run 235/70/15 front tires? Those are 28" tall, a very large front tire. 235/60/15's are 26" tall, still a big tire, but a full 2" shorter in diameter. Those would really help your clearance issues.
Your front wheels are fine.

no not necessary just wanted to have them match rears, and I thought the 60's would look small also spoke to Wilwood and was told that if I change to OE Disc brake spindles that should resolve the issue, anyone heard that, I plan on calling to get another opinion if it would work I do no mind, cheaper than 2 more redlines,

I would hazard the guess that a lot more people are running 235/60's on the front, than 235/70's. It's your car and your money,though.

What spindles are on the car,now?
