I much prefer the look of 18x10 on all 4 corners but ruts in the road made steering the car at slow speeds too much of a chore.

It's not that bad honestly. My '00 z28 has 275/40ZR17's on it that are similarly wide (slightly smaller width) so I'm used to the cars tracking uneven pavement.

Thanks.. Left the centercaps off because I dont like how they look with the red corvette emblem. I'm debating if I should try painting the emblem black and/or if there are any aftermarket centercaps available.. I don't like any red on the exterior because it provokes the theme of ketchup and mustard (or atleast in my mind )

I looked thru the photos I took and this is one I didnt post.. Otherwise no I do not currently have a closeup of the front fender. The front DOES "poke" out more than I'd like but it's livable. It's right on the border of being acceptable. I decided I was willing to deal with the less than perfect aesthetics in return for better handling and tire rotation capability. I bought the car for function more than form.

Oh I totally agree on the function over form. If you ever get around to it please share pics! Thanks again

Why would 18/18 cause TC/AH issues?

Is it just an 18/18 issue?

Every time I open a thread here I find a new way to spend money

Looks great. When I wear out the continentals on the rear of mine I will seriously consider doing this.

Looks awesome!!
I went with the 18 X 10.5 wheels all around about a month ago and so far I'm loving it. I went with 275 up front and 315 in the rear and no problems so far. I got a good deal on the tires or I would have tried the 285 up front like you did.
I haven't tried lowering mine on the stock bolts yet, but, plan to as soon as I have a bit of time. I see you went 'all the way' on the stock bolts. Any problems that you've noticed so far? Is ride quality and handling OK?
Thanks!!

Probably a corvette forum myth. They say that you're supposed to have a ~5% difference in diameter front to rear to avoid TC/AH problems. I don't know anyone face to face that actually has such issues- in fact CF is the only place I've heard about it happening. I've been running a square setup for a while and on the track often ran a front tire that was 1 or more inches taller than the rear and used TC/AH and still had no problems. Granted I wasn't doing 200mph runs either...

The ONLY way I got TC/AH issues was when the front tires were completely stationary and the rears were doing 50kph+ on a Dyno (Forgot to turn the systems off).

I love the square 18's look. Mine still has 17's in front but I actually prefer the look with out center caps.

It has nothing to do with wheel size and everything to do with tire size

It most certainly isn't a myth. 97-00 cars have a different traction control system than 01-04 cars, and the Gen 2 system is much more tolerant of shenanigans than the Gen 1 system. I have heard of very few people who have had any TC/AH issues due to tire sizes on Gen 2 cars, but one guy showed up here with a bunch of errors after a shop rotated his factory rolling stock once

yeah I could not find enough FACTUAL issues to justify avoiding it. I wanted the square setup for tire rotation and handling characteristics. I did not like the car being prone to understeer rather than oversteer.

Are those polished or chrome rims? Looks nice!

I like the look without the centercaps too but I wish there was some smaller aftermarket centercap that would cover the hubs where the screw type thing sticks out in the back. Basically a centercap but a smaller diameter.

I'm not sure, they look chrome to me but I was informed that chrome wheels never came on C5's. Either way I like them.

Oh, I wasn't advocating avoiding it; worst case scenario, you just turn the nannies off

I was just explaining why you never see tire sizes causing issues in the Z06 forum; we all have the Gen 2 TC with Active Handling
