Do I run the risk of rubbing at more modest steering angles?
Leading evidence: 'Run risk of rubbing at more modest steering angles' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace with lowering' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I run 26" ground to top of wheel well all four corners (of course maybe slightly different with a proper corner balance).

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 996 C2 has been lowered to GT3 height with the aid of H&R coilovers. The front tires are 235/40-18 on 18"x8.5" wheels. My tires rub on the fender liner at steering angles that would seem to be well short of steering lock. I encounter this mostly when doing things like parallel parking, or backing into a perpendicular parking spot.
My concern is more about what happens when I get this car out on to the track and the suspension is more heavily loaded in corners. Do I run the risk of rubbing at more modest steering angles?
I run 26" ground to top of wheel well all four corners (of course maybe slightly different with a proper corner balance). Works great with my PSS10's. I've been lower before, but it is really hard to drive around without scraping the hell out of your front bumper.
How do you know what his offsets are? Those appear to be GT3 wheels which work just fine under the same NB front end....
FWIW mine rubbed like hell on the OEM liners so I went to the cup liners which are taller allowing more clearance. They still rub at full lock. Cups have restricted steering racks so they can't turn anywhere near as steeply as a street car....
Excuse me. I "suspect" the offsets are wrong for the car. Since the tires are rubbing and all.
Yes they do look like GT3 wheels that are "different" than stock C2 because they are wider and require different "offsets" so the tires don't rub on a stock C2.
As you pointed out, cup liners will work as well.
Better?
I have lowered mine on factory rims and stock tire sizes - I'm 25.5 inches top of tire to ground all around on a 225/40/18 front, without issues.
It's your tire size... (hint) They are slightly wider - by 1.25% from factory stock. You may have to get a slight offset adjustment if it bothers you too much. Right now you have 9mm LESS clearance on the strut side, and the outside edge of the wheel extends an extra 3mm.
I must be an idiot on this subject... If you are measuring top of tire to ground, how does that change with lowering... Sorry for the stupid question.
Also, any benefits to slightly lowering a stock driver that are noticeable or is this just something for the hardcore folks? My car has 168k and probably due to have the suspension looked over... May upgrade or just stay stock.
Thanks in advance,
JKC
You don't measure just the tire you measure to the bottom of the fender.
As for the benefits, it provides more crisp and precise handling but often with the tradeoff of a rougher ride. It all depends what you want out of your car and whether to upgrade or stay stock is pretty subjective.
If you like the ride height you're at now, make it work for you. A little rubbing here and there really isn't that bad as long as you're not rubbing on a sharp piece of metal or something.
Take the wheels off the car and look for where they are rubbing. It should be pretty apparent by the shiny/smooth areas on the fender linder where the tires have rubbed. Then get your heat gun out and heat those areas. Once the plastic is pliable, push it back a bit to indent it and give you the clearance you need. Or, trim it with a razor blade if it's rubbing on the edge of something.
the question is, much that much lowering, are you gonna invest in the dog bones to correct your camber ? or are you gonna let the road eat your tire's inside within 5k miles...
Huh?
Compromising functionality for looks is........... well, I've already been scolded for using mean words, so lets say it's....... not sensible.
If you're looking to improve perfomance then you should do it right. I don't think you're allowed to track a car that has tire rub.
There's a big difference between a tire rubbing ever-so-slightly on the plastic fender liner under full lock/heavy load and rubbing the sidewalls on the fender so much the paint burns.
Well, then he might have some more work ahead him in that case, huh?
Do you feel mighty and intellectually superior now? I award you one internets, sir.
Thanks Captain - that's a great idea. I'll apply heat and see if I can make that work. The rubbing is limited to the tire contacting the upper middle portion of the fender liner.
Well, for $2-3k and a few possible headaches, you can get to 25" too.
Get your minds outta the gutter, I'm talking about the car
(my guess is it would cost closer to $20k to get 25" there, not that I've looked into it or anything. What you heard is NOT true!!!)
