Front end wheel clearance differences on 68 Camaro's...

Hi Guys,

Quick query....

I have read enough to know that everyone has different experiences (and results) with tyre and wheel clearances on these old cars. Common backspace measurements may work on one, but not another.

Anyhow....

Just borrowed some wheels to do a "test fit" on my 68 camaro.

Has ridetech control arms, spindles, tru-turn and shocks on the front.
Also has wilwood brake upgrade.

Wheel tested was a 17x8 with 4.75" of backspace.

I do understand these items I have installed mean my car is far from standard and common measurements may not apply. For example the wilwood kit changes my track width a little, but tobin @ Kore3 said mine is fractionally changed from std - nothing to worry about.


So - to my issue....

I am noticing a fair difference on the outer wheel arch clearance between driver and passenger side on my car. Drivers side has much less clearance on the outside arch v's passenger side.

Passenger side is clearing comfortably, and will do so even better once I install the button head bolts for inner fender.

The drivers side is hitting the lip of the arch already - pretty much where the screws hold the chrome trim to the arch. So wheel is hitting well before the inner bolts.

The drivers side was so different to the passenger side - I thought one of the wheels must have the wrong backspace, but took the wheel off and measured - it is 4.75" BS.

Can I ask what differences other have seen between clearances on drivers and passenger sides for front wheels???

Just wondering if what I am seeing is what others would call acceptable or "not uncommon".

The wheel locations in relation to the fender are noticeably different on mine.

Thanks in advance for the input.

Cheers,
Shanan

Sounds to me like your sub frame isn't centered. Or possibly replaced fenders(?).

Re: Front end wheel clearance differences on 68 Camaro's...

So not to ask the obvious question but did you measure the overall width of the wheel itself? Perhaps even with identical backspace you grabbed both a front and rear wheel? I know this is probably a long shot but all things being equal either you are using two different wheels which you think are the same due to equal backspace or your DS fender is out of whack (which seems much less likely).

Check your alignment... Positive camber can place the tire closer to the fender lip and negative camber will provide more fender lip and tire clearance. That said, a bit of negative camber is a good thing, it helps with fender lip clearance and keeps the contact patch planted in the corners.
