Fitment issues with 285 35 18 69 DSE

[colorado80439]

So I'm in the middle of a build with a 69 Camaro DSE subframe hanging the fenders and modding the inner fenders. I have an 18x10 rim 6.25 backspace and a 285/35/18. The car is on jack stands and we pulled the shocks off to look at fitment through the full range of travel. If I raise the tire into the fender about 1 inch from the upper bump stop, I can only turn the wheel through less than half it's turn radius before it hits the fender at about the 2 o'clock or 10 o'clock position depending on the direction I'm turning the wheel. They are GM fenders, planning to roll the lip which will give a little more. The camber is set to DSE's initial set up which definitely negative. Spoke with DSE and they recommend a 275/35/18 with 6.125 backspace and they say with the 275 set up it will probably rub in some situations, but again I'm only getting half my turn radius when compressed 1 inch from the top bump stop. Is this normal? Will I never be that compressed when into a hard turn?
Thanks in advance, Dave

285 with the fenders trimmed still touches. On my 67 I have 275s and mine will rub at full lock. Thing is I’m running 1.5 neg camber.

Ill bet I'm at least 1.5 degrees of camber and I'm good at static ride height, I worried about when the suspension is compressed then im into the fender at half the turn radius
Thanks for the reply

When the car is at ride height, how much space do you have between the tire and fender? As a general rule of thumb, we've found that when turned, with plenty of compression travel, about 1.5" of clearance is needed.

This also depends on how low, or high, the static ride height is. Do you have some photos you can post up?

Good to know, I'll get some pics posted next week
Thanks again for the input

Looks like at ride height we have 1 inch of clearance. Looks like we will go with that and raise ride height if needed or increased spring rate. Thanks for the help

Did you get this sorted out?
