19s(rear) 18(front)

[Cannibiz]

Has anyone put 19s on the back and 18s in the front? If so I really want to see this. Upload pics please.

I've seen 19s all around but no staggered 18/19. There aren't many people here running staggered diameter wheels in general. Jut staggered widths or square widths for the most part.

With the right wheels and aero, 18/19 would probably look pretty good.

It's what I want to go for. I just would really like to see it first. But it's looking like I'm going to have be the ginny pig.

My question is, how does 17f-18r or 18f-19r stagger affect handling? I would imagine that contact patches would be similar in size, but rolling circumference is no longer equal. How does this change balance? I guess the increased thermal capacity in the rear would mean better stick for longer track sessions, so would that make the front understeer in general? Anyone know how this is tuned in exotics that have different F/R sizes?

I have no clue. But I will post about my experiences. I plan on doing this sometime next month. Also I drift. So no track days but still plenty if fun.

The car was designed to run a square setup. I have yet to run anything other than a square setup on this car. That being said, I don't really know.

I ran 17/18 staggered on my old s14 and loved it though. I've thought about doing the same with this car

I would like to see or try this also. The old supercars did this in the 80's. It must have made sense somehow.
You said yourself, your s14 also was not designed for staggered wheel sizes but you loved it. No harm in trying this out.

With proper tire choice you can keep the front and rear tire diameters pretty close to each other.

If the front-to-rear diameters are too different, it will freak out the traction control and DSC.

It would look very cool though no doubt.

Haven't seen this on this car, the 98 corvette in the garage has 17s on the front 18s on the back and it looks good and handles perfectly. Be curious to see it on this car though

Is going to look sick! Those rear tire profiles are going to be pretty thin though. I'm willing to bet if you don't have your suspension perfectly dialed in, with lightweight wheels/tires, your car may be more prone to becoming unsettled at high speeds when going over bumps/swails on a less than clean track.

I'm not going to take out on any track days but , I drift a lot. I have stock suspension. And I'm not going to lower it. So I might (big might) be able to get some decent meat back there.

Just because you have a different rim diameter doesn't mean the tire diameter is different. You can easily size the tires so that you have staggered diameters AND widths but very close final tire diameters.

Most exotics have staggered widths to account for traction and weight distribution needs, staggered diameter would be strictly for looks.

Staggering widths will change handling balance (more width out back will mean more rear traction, so more understeer), staggered diameters won't really change the balance at all assuming you run the same width tires at each corner.

Cars that come from the factory with staggered whel diameters also have different tire diameters. If you keep the same or similar tire diameters, fronts will have taller sidewalls and will look beefier than the rears. I went staggered-diameters on my FD in order to run 275s in back (245/40-17, 275/35-18), but that car is 50/50 with 500+ hp and no traction or stability controls to be affected.
Anyway, on a 55/45 200hp 86, I wouldn't bother going 18/19. It won't look as hot as you might think...

I agree with this. If you want to keep stock diameters to keep your traction control systems, speedometer, etc. functioning as intended, you will end up with front sidewalls that are 1" taller than rear sidewalls. Front will have a meatier look and rear will have a low-pro/rubber band look.

But if you don't care about throwing your systems off balance and want to follow your vision, don't half-ass it... do it all the way! Put meat on both front and back sidewalls so they look similar (rear will end up taller for more rake). I believe the rear wheel opening looks slightly larger than the front to accommodate more wheel/tire. Here is my car that looks slightly raked even though front and rear are dropped at the same height and tires are square. It is because the rear fender flares outward more making the wheel look tucked and the rear wheel well opening looks slightly larger than the front (maybe due to the short overhang of the rear bumper). Though I wouldn't do it myself as it kills some functionality, a larger rear wheel/tire might fill the rear better, aesthetically.
