So is it the Ridetech suspension that is allowing for more room? I assume with stock suspension we can't fit 315's like that.
And BTW, your car looks AWESOME!!!
Our rear arms are offset inward in the area where the tire would contact. This allows more backspacing to be ran on the rear, allowing for a wider tire wheel combo.
No, The extension and compression is controlled by the CoilOvers. They have a compression bumpstop on the shaft, and an internal bumpstop for the extension.
Does the compression bump stop keep the tire from hitting the fender? Do you risk fender contact issues with a taller tire?

With 18x10s and 295/30 or 35 tires, I never had issues with the front tire rubbing, even under hard compression. The rear does have some rub marks on the inner but my camber settings play some role in that and even still, it is relatively minor. This is also on a road course at race speeds with a passenger in the car.... Not sure it would be an issue with spirited driving on the street.
I'm speechless. I love the way your car looks with the Welds. I was hoping someone would do it, and you beat me to it. They look incredible. Love your car. I'll be ordering the same size wheels for my '76 in January, hopefully.
Curious if you think I could get away with the stock A-arms and rear trailing arm for those 18x10.5s. I'm not familiar with whether or not they are much of a restriction for wheel and tire clearance.

Thanks for comment. I'm not sure how much room the stock arms have. I know someone local who has a 78 and we wanted to see if my old 18x10s fit his car with stock suspension. If we test them I'll report back.

Fingers crossed that you have time to! Still can't stop looking at your car.

I would love to see this too! I am looking for wheels and for the price have settled on E-T LT III wheels. Would like a 285 up front, wheel size in 18x9-10 inch range. Rears Im looking at 18x12 but have flares that need filling so I got measuring to do there.
Note, the 18x10 American Racing PVD finished wheels (5.75" backspacing) do not clear front Baer 14" 6P calipers without a 1/4" spacer. They just barely rub the edges of the caliper. If the spoke did not curve in, it would have been fine. The rears had plenty of room.
My new custom American with the correct 5.5" BS should be sitting on my door step when I get home so hopefully they fit correctly.
This is with the 1/4" hub/lug centric spacer
Did you ever get the TTii with 5.5" back spacing? Is so did that fix the rubbing? Any pictures? The .25". spacer did the same effect I would imagine. Are there any issues with spacers? I have the extended wheel studs so plenty of threads. I'm planning on purchasing TTii Friday and already have 295/35/18 tires.

I did purchase 5.5" backspace wheels but still had a rub and required a 1/8" spacer from Motorsports Tech. The issue is how the TT2 spokes curve in at the wheel barrel rather than being straight to the outer rim. The Welds are 18x10.5 with 5.5" backspace and have tons of room, like stick my hand between the caliper and spoke kind of room, so it just depends on the wheel I guess.

My 68 convert came with American Racing Torque Thrust II 18 x 8 inch with 255/40 tires on the front and 20 x 10 inch with 295/40 tires on the back. one inch spacers all around with stock brakes. Photo is dealer's in perfect lighting.

I can say this, the 18x10s fit both the front and rear of the stock suspension 78 with no spacers and no rubbing. As would be expected, the front rub at full lock but beyond that they did clear, even the trailing arm if just barely.

Correct 5.5" BS. Sorry, not my car but I do seem to remember he did not have a front sway bar. Yes, the car was put down on the ground and checked though. His car was on stock springs and sat really high. The trailing arms were where the clearance seemed the tightest.
Thanks for that. I'm not sure I get the whole measurement part correctly, so please correct me if I'm wrong, but would that mean your 18x10.5 5.6" backspace Welds may fit as well? Or would it be too tight?

It seems they would likely bolt up. Not sure on body clearance though as they will stick out 6/10" more than these wheels did (.1 for the difference in backspace and another 1/2" for the wider wheel).

At static I don't believe so, but can't say for sure, unless you take the camber curve into account during compression. Honestly, on my car, the wheels fit inside the body lines better in the front than the rear.
