Hey folks,
A question for you gurus, I came across local forgestar wheels,
Front: 19x11 with 275/35/19
Rear: 20x13 has 345/30/20

Will these fit on a stock ride height 99RT10? I’ll be looking at getting slightly wider front tires eventually (maybe 285’s) but wanted to have minimal wheel gap and no rubbing issues.

Want to be sure that the existing size with tires will fit without any modifications.

Fronts are going to be fine. You have to get up to 305/315 width before you have any concerns. The 345's are likely to rub the fender liners out back if you lower it very much. I think many folks lower the car to close the wheel gaps with OE 26" tires. Going to the bigger wheels, your tires are going to be closer to 28" diameter and will fill the gaps without having to drop the suspension ride height excessively.

Gotcha, Im not planning to drop the car (roads and commercial driveways in houston are bad) so it'll remain stock ride height.
So I take it the sizes will be fine with no rubbing? That is my major concern. I wouldn't need spacers or anything?

I understand the gearing is going to change with bigger wheels but I only cruise and make short weekend runs so I might be able to handle it for a while.

I have 285/35 and 355/30 both 19’s.. Lowered on BC coilovers with Swift springs with zero rubbing.. Offset of the wheels is also going to make a difference in whether it rubs or not. But on tire size alone, shouldn’t be an issue.

^^^ You probably have stiffer springs with the BC swap. That helps keep from bottoming. Stockers are not very stiff, and have a lot of bushing preload set up to help rebound, but not bump.

Got these installed, looks good. But had to use the stock lug nuts, in chrome. Prefer going to black lug nuts, any recommendations on a set that are black? Locking ones might be better.

got these on, for anyone in the future searching
Forgestar F14's, stock ride height. Color is a dark bronze (Bronze burst) - but in the shade they look black.
Front: 19x11 with 275/35/19
Rear: 20x13 has 345/30/20

I'll get some before and after side profile pictures

FYI, with coilovers you can dial out the front rake and actually increase front ground clearance while lowering the car.

What offset did you end up going with?
To be honest, I found these wheels used from a local gen 5 viper owner and purchased them. He said they were ET +62 rear and ET+43 front
The wheel/alignment shop did dial in slight negative camber front and back.

Awesome thank you! I will make a note of this on the coilover setup. thank you!
