well i have seen plenty of fat setup for 19 on GS, how about fat setup for 20s on GS? is that ok? manaray i am sure you have most info on this

also, how about fat setup on 19 for IS? is that ok?

obviously i want big rims for my cars, but i want more ride quality back if possible

Manaray

The Fat setup will NOT work on 20's...and on the IS, I don't think the IS can support 20" size wheels (Which is what the Fat 19" setup basically works out to...)

For ride quality, the Fat 19" setup is the way to go...also has a little more rim protection...that being said, I'm still doing 20's on my SC.

hey thanks manaray, you simply did the decision for me 20 on GS and 19 on IS and no fat setup for both i won't compensate on rim size at all, hehe

Manaray

Since you've been driving on your "standard" 19" setup for a while now, you should NOT have any problems...I mean you're used to not driving 50mph over speed bumps and also looking out for potholes, right?

haha yeah, very true, i am used to driving the gs4 with 19 so carefully, even my gf. just that my parents are coming over soon so i was thinking if their butt would like it

Manaray, the fat 19 setup on GS being 245/40-19 (19 x 8.5 -front) and 285/35-19 (19 x 10 -rear) right .....? Higher side wall to maintain better ride comfort. Would this setup require any fender rolling at the rear?

Are there any alignment issues with this setup (negative camber) ? If yes, what size should I stick to maintain correct alignment? Is this alignment issue very big?

An aside question - Manaray, what kit do you have on the front of your car? It looks absolutely awesome in black. I wonder what it would look like on a Silver car............

Does anybody have a picture of a fat set up on a GS3, with a slight drop. I myself is considering to go with this route due to lots of pot holds around here. But before making this decision i would like to se this set up. I order my rims last week, some IForged 19, flux they will be here in a bout 6 weeks so i have time to order my tires. I really like the look of 245/35/19 front and 275/30/19 rear.

i think with that setup you should be fine, but you might want to put 275/35/19 at the back arather than 285. depending on the offset 285 might rub bad.

with fat setup you need to raise your car a bit higher than 19" with normal setup so you shouldn't have to worry about camber

manaray has classy sport design body kits on his car

Hi Henry,

Thanks for the reply!

Does that mean that I should stick to 9.5 inches wide on the rear rather than 10 inches?

I don't understand what you mean by this "with fat setup you need to raise your car a bit higher than 19". Raise my car higher ...........? I have done the L-tuned suspension/springs mod on my car. Please explain what you mean by that sentence.

nonono, you can still have 10, but having 275 will prevent you from rubbing better than 285. depending on what tires you get 285 might be too wide. a lot of people are running 10 in the back with 275/30/19, so 275/35/19 will fit as well

the overall diameter of the wheel (not rim) of 19 with 275/35/19 will be about 1" large than 19 with 275/30/19, so 1/2" on radius. i thought you had coilover, if that's the case you might wanna raise the car back up by 1/2" to compensate the increase in overall diameter, but since you are on springs/shocks you are fine

and no, camber won't be affected as far as i can tell

Hameed

The reason why I asked about that is because I read somewhere that with the 285's the sidewall is more straight on a 10 inch rim than the 275's. The 275's tend to curve inwards at the outer part of the tire........

And if that is the case, then I better stick with 275's as I don't want the tire to curve inwards...

Manaray

Henry pretty much covered it....let me add that a 285 does sit better on a 10" wide wheel in terms of side wall "straightness" but depending on the tire, a 275 doesn't look all that bad. I'm running a 275 on both sets of 10's (on my GS430 and SC400)....the nice thing about running a 275 is that you can push the wheel out to the fender just a tad more w/o making the tire look too stretched (like when they put a 255 on a 10" wide wheel...)

Now you CAN do a 9.5" wide wheel in the rear to give the setup a more "square" look but also your tire choice will make a difference....Nitto's, for example, are very square....Toyos are more rounded...

fboukari

I'll run fat setup and I'm wondering how much can I drop the car. Was thinking abou 2 inches.
Will I rub?
Manaray how much of a drop do you got?

yeah like manaray said it depends on the brand too. i know yokohama is pretty sq

hey manaray, so in your opinion, how's the so3? that's pretty much the brand i wanna get, are they sq or more rounded? and when you say so3 is meaty, what does that mean?
