Tucked in rear wheels/tires

[dtheo]

How do I get this tucked in like below? What camber?

Your 350R has pretty wide rear wheels with a significant offset that isn't going to allow that much. You'll probably have to switch wheels, or change the rear suspension geometry. Rear adjustable camber arms at a minimum. Definitely the wheels.

Due to the camber curve the wheels will do that naturally as the suspension compresses. Are you still on stock suspension?

This is my car on 325mm rear tires on an 11.5" wheel and stock camber, just lowered on Ford Racing springs.

Go max camber, it will tuck. Probably like -2.5.

Btw, your stock camber arms should get you there. At least to -2.

What offset and tires are you currently on?

With some basic geometry you can calculate how much X° of additional negative camber will move the top of your wheel/tire inboard. How many mm or inches do you want to move the top of your tire?

Or buy 11.5" wide wheels with ET61 like I did (i.e. pulls the wheels in 5mm compared to OE carbon wheels). Neg 2 degrees rear camber, 315s, pretty much perfectly flush.

Not taking a shot here, but it’s funny how most folks with cars that come tucked in are looking for the flush look with spacers and wider wheels/tires. Only a guy who has that sexy look stock would want to pull it back in…to each his own, just an observation.

If I recall correctly, Carbon Revolution couldn't satisfactorily make the rear wheel pad (i.e. what mates to the hub) narrower with the technology they had at the time, hence the rear poke. By the time they developed the GT500 CFTP wheels, the carbon wheel technology had improved and they don't poke (and weigh about the same as the 19" 350R wheels despite being 20" wheels for the CFTP).

Not a GT350, but just ordered SVE R350 wheels 19x11 w/ 325/30's on them and I'm assured, repeatedly, by LMR that they will not poke. Hope that's correct. They're 50mm offset on the rear 19x11's.

Yes currently stock suspension with 325rears on R rims.

Well there's your issue. You went with wider rears and made 0 changes to accommodate.

Honestly your options are as follows

- deal with it
- alter rear suspension geometry for looks (should alter front to match new revised handling characteristics)
- downsize to stock tire sizes

I'm assuming you started this thread because you're interested in option 2 which means you have 1 of 2 options.

- lower the car which will bring the tires in more as the suspension gains negative camber when lowered
- leave ride height the same and alter rear camber enough to get the visual look you're after with an adjustable rear camber arm or seeing if you can get enough movement out of the factory adjustment range

Every one of the photos you showed above are for significantly lowered cars so if that's the style you're looking for then springs are going to be a part of your answer.

Yea Mavisky, when I bought the car is had 325 rear so might need to get smaller ones.

 

[wingnutt]

…and all 325 tires are not the same. I’m running Eagle F1s and they poke more than that, but I’m past the hella flush phase

 

[K4fxd]

The stock rear adjustment will go to -2.5. This should be enough to get the look you want.

The rear suspension width on the 2 cars is different. It's an E brake thing: electronic vs manual. The wheels are also different. The GT500 CFTP wheels stick way out on a GT350R.

The CF wheels in the R aren't going to tuck IMO. But for the OP, please let us know how it goes.
