Be ready to take your spacers off and raise the car a little. You may or may not have to. I gotta put my coilovers on one day soon.

Idk about lowering, but on stock '12 touring sport ride height I have 10mm spacers upfront, 2.5mm spacers in the rear...making my effective front offset +30mm and +20.5mm rear on 285/35R19 / 325/30R19 tires with no rubbing and a prefect flush-to-fender stance.

Did you guys need more than 35 psi on the tires when running them oversize like this? I got 265 RE-11s on a 9 inch front and at 35 psi it looked half-flat. 40ish looks better.

:icon14:

Noop, stock pressures.

ditto

The tires are wider than original so yes they're gonna look more bubbly on the wheels and therefore look more underinflated. But...they're not underinflated. Infact, the tires having a larger surface area would require less psi in them to hold the same amount of weight, so stock pressure or less...but not more and certainly not 40psi.

Anyone running this set up 285/35R19 (F), 325/30R19 (R) with Swift Springs?

i always stick with the factory sized tires, the engineers have it figured out.

Ah, no they don't. My car is basically stock. It is a big difference. It is not always about the engineering. It is about the money (bean counters).

Not exactly. It depends on what you want to get out of the car. The engineers have to account for too many variables in their design and execution to maximize the Z's performance. Safety requirements and cost are probably the most severe restrictions.

Engineers did a superb job on the concentric slave cylinders ;)

This.

If you run stock wheels I dont see why they wouldn't fit without spacers

:iagree: As well as the heat soak issues with the VQ
