18 or 19...1994 GS300
Have a 94 GS and will be ordering either Tein or JIC coilover. Also ordering Work Euroline Dh wheels in 18 or 19. Plan on lowering the car about1.5-2.5" and wish not to have to modify the fenders (although I will if there is no way getting around if for the look I want, but REALLY dont want to) . Based on this what wheel widths would be favored? What are the benefits/con of running a staggered set up say vs. 18x8.5 all the way around.
Roads around here are kinda of bumpy, no so many potholes, just lots of bumps. Im scared of bending a wheel. What tire size would be ideal. I was thinking 40's. I've seen Rominl post a few times and for the rear he always recommends a thinner sidewall. For example: 245/35/19 and 275/30/19, why is this?
Without researchin I was lookin into 19x8/8.5 in the front and 19x9/9.5 in the rear. But since I plan on lowering it and have been hearing alot about 19's rubbing and having to do fender mods, I've been reconsidering and thinking about 18x8 and 18x9.

Thanks. Looks like I know have 2 threads in this forum. I had made one in the brake/suspension section since the question involved coilovers, and then made one a week later looking for more insight. Turns out my original thread just got moved here.
How would I go about making a decision about what size to buy? I have a little understanding about wheels, but not much and am more of a hands-on learner, so please be patient if I dont understand right away.
First off, I need to decide 18 or 19. I know 19's will be big enough, but 18's Im unsure of. I'd rather go with 18s due to being cheaper and tires are cheaper, but Im not sure if it will look how I want. So can anyone show my pics of a 1st gen GS on 18's and one on 19's?
Second, wheel width. I think I will end up going staggered. This will most likely end up with me rolling the fenders. Can anyone tell my how much it cost them to get their fenders rolled? What is a common wheel width for staggered set ups. Im not lookin for something that REALLy wide since I will only upgrade the intake and exhaust until I do a 2jz-gte swap. Does 8.5 front and 9.5 rear sound good?
Third, offset. This is kind of where I start to get lost. I under stand that the lower the offset, the more of a lip. But doesnt it also have something to do with the width of the wheel. Like a 18x8.5 +38 could have the same amount of lip as say a 18x9.5 +32. What's a common offset to have about a 2" lip.
If I did end up gettin 18x8.5 front and 18x9.5 what side wall would be good tire width/sidewall. On my Supra wheels, 16x7.5, I had 225/50/16's all around. Im still kind of confused of why you would put a thinner sidewall tire in the rear if both wheels are 18".
Pics/specs would be greatly appreciated to.
THANKS!

Will that apply to my GS? It states at the top...
98-05 GS300/400/430
01-05 IS300
02+ SC430
If it does apply to the 1 gen then I dont understand why it wasnt added. I have a 93-97 and keep getting directed towards 98-05 information. I'm not critisizing in anyway, just wondering why it says 98-05 instead of 93-05 if it does infact apply to the 1 gen. Just kinda creates a lillte more confusion for the user.
Ya I already briefly looked over it, but then exited out of it because I saw it said it was for 98-05 GS300/400/430, and didnt include 93-97 GS anywhere in there.
Just read over, looks like it will be a big help. But one thing it didnt cover and I still dont understand is why have a thinner tire in back for a wheel that has the same diameter as front?

Still, the numbers should be close and there is general information about offset and sizing as you have found out on further reading.
As for the tire sidewall, I covered that in a post above:

k, I got the math figured out and ran 275x.35 just to see what number popped up and it was 96.25. So would that mean the actual sidewall height would be 96.25mm for 275/35 and 85.75mm for 245/35, therefore resulting in actually having a bigger tire in the rear? Thanks for your help, one of the first times technical info has actually made sence to me over a forum
