Current set up: Lexus g spider 18x8.5 +45 all around. Front fenders are untouched (minus the blow dryer to the area where the tires rubs the fenders when 20's are on). My rear fenders are pulled and rolled a little bit and I am running a 25mm spacer. I would say I could have went with a 30mm spacer and been flush. My 20in Vossens are 10.5 +45 in the rear and i probably could run a 5mm spacer.

With all this said, would I be able to run a 19x9.5 +12 offset in the rear, for a flush look, no rubbing, and no negative camber?? Front I would have 19x9.5 +22, which I'm not even sure will fit/rub or not.

So 2 questions. Thanks CL for always being helpful.

Questions about tires will come later.

*Update* I plan on getting 19x9.5 +22 offset all around. Look at bottom of page for tire question.

 

Vossen cv1s rear offset I have actually might be +42 in rear not +45...not exactly sure but I think vossen only make 1 offset for the rear, +42.

 

good luck, its going to need work

 

What wouldn't work the rear or front? If its the rear I would just go +22 all around. I def don't wanna pull the rear fenders more.

According to the wheel calc..compared to vossen front wheels, new front wheels: inner clearance-10mm and outer position-extend an extra 22mm.. new rear wheels: inner clearance- 36mm more and outer position- extend 10mm more. So basically they both will be rubbing??

 

If they rub I might go with 18x9.5 all around..rear wheels extend 3mm more in the rear compared to my gspider +45 offset with 25mm spacer, so I think I would be flush there. Compared to the Vossen rears it would be 1mm less aggressive. Compared to Vossen front wheels these front wheels: inner clearance- 2mm more and outer position- extend 14mm more. That's the info I got...any suggestions? I would rather have 19s but if its not possible without more fender mods, its a no go.

 

This weekend I lowered my rear and checked how many millimeters i have to spare for a more aggressive set of wheels. From what I found is that I unfortunately will not be able to fit the +12 offset in the rear, 2mm too much according to my measurements, but I will be able to fit 19x9.5 +22 offset all around. If i pair that with 245/35/19 tires would i be rubbing? Right now im nowhere close to rubbing but im running IS tire set up 18x8.5 255/35/18.

 

2mm? you can make that fit.
stretch the tires, and yank those fenders. shame to give up the look you want over 2mm. though, function is not my strong point when it comes to fitment. i rub like crazy. lol.

 

negative camber alone can take care of 2mm

 

Yeh its true, but how much negative camber though. I don't wanna run through tires.

 

My main objective is function then fitment although I want the best fitment possible. Will I be rubbing with 245/35/19?

Also I never realized I have to get new tpms programmed. I have 2 sets of wheels and didn't bother to get either of them programmed, but the light on the dash goes off and resets sometimes even though my stock wheels w stock tpms are about 100ft away locked in a tool shed. I'm not even sure if I should get tpms in the new wheels.

 

I have to disagree that function is the main objective. Not if you're trying t run super aggressive fitment and using spacers. Aggressive fitment is for looks. You can't run the slalom course with super aggressive fitting wheels. Not if you want good performance.

 

I'm not trying to track it or anything like that, I just don't want to have to baby it when I'm driving on these nyc roads like I had to with my 20" vossens. I want to be able to drive like I do with my 18"s..I want to be able to hit a bump without cringing and wondering if I bent the wheel. I also want more style/flashiness than the 18"s g spiders I currently have mounted.

 

If you're so concerned about trouble free driving, why are you trying to get aggressive fitment?
