Default 205/55-16's Major Rubbing

About 5 years ago I put a Tokico shock and spring set on my car. At this time I was running 195/65-15's. Although, this lowered the car around 2 to 2.5 inches I didn't have any rubbing issues.

Now, about a week ago, I put 205/55-16's on some 16x7 +25's and now I am having rubbing issues when the body flexes. The tires do not rub the wheel well when I turn though. Mostly at high speed cornering.

My question is...what could be the reason and what are the options to fix it?
The 2 solutions I have come to are a shorter tire or adjustable coilovers, so I can change spring rate/stiffness and/or ride height.

Any advice is greatly appreciated and welcomed.

BECAUSE YOUR TIRES ARE HUGE, and yes i just yelled at you. 45 profile tires MAX in 16 inch wheels.

You need to read around here a good bit it seems.

205-45-16 tires should be on the top of the list.

Tires might be ok size. I assume it's on an accord. Could still be a little big though. I'm sure the +25 offset isn't helping either

Offset and tire size is what is making it rub. I'd bet on that. Think your sidewall is 112.75MM a 45 sidewall is 92.25MM, 20.55MM difference or .8" then think thats on every part, thats a huge *** tire on a 16" wheel for a car like that lol. Then +25 offset and a 2" drop your going to need some camber to pull that in. Post a picture of this please

dont listin to any of the civic guys giving advice for a accord

I really dont see how you can have any problems with this set up at all ...compared to my last set up you are about the same except you have 4 more mm of sidewall on the tire than i did ,-15mm offset than i had but your rim is .5 inches in the width less than mine was, also you have a skinner tire than i had and your about the same height that i used to be...i had no issues what so ever on rubbing and actually had a huge *** gap between the top of the tires and the fender...did i mention i was on soft stock shocks with 150,000miles on them

now on my new set up im lowered at least 3 inches all around on 17's with 8.5inch wide rims with a 20mm offset on 205/45 tires (that means im on a taller tire) and i still have no rubbing issues with lightly rolled rear fenders and virgin fronts, also im running less negative camber than natural on the rear

also about those coils you want to buy....if those are the spring rates i highly recomend you get stiffer ones than those...in front im running 12k and in my rear im running 6k and i love it

and just like the guy above my first post Please post some pictures

I'll take a pic of it today when I get home. The setup I am currently running suspension wise is what I described in my original post. The coilovers I'm looking at are adjustable from 3kg to 22kg. I believe they are 14kg front and 9kg rear right out of the box. I haven't tried to adjust my camber mainly because the shops around here can't get my car on their lifts without scratching the **** our of my header and exhaust.

Just Click the link and you should be able to go through all the pics. They won't upload for some reason. I'm using a mac, but I wouldn't think that would cause a problem.

Im having a hard time believing that your springs are 9kg/mm in the rear and your rubbing with a finger gap. What kind of springs are they?

x2. the tire size is justy slightly bigger than stock. but the +25 offset is most definitely your problem

The springs I'm running are not that stiff (9kg/mm). I don't know the exact specs, but they are really soft. The manufacturer is Tokico.

.
why dont you go to a alignment shop with a lower rack then, and how does it scratch your header if the only place the racks have their ramps is where the tires are and the middle section doesnt have anything to scratch on

^this...im running 6K with a half a finger gap and haven't had one problem with rubbing at all with minor rolled fenders

the tires are 2mm diffrent in height than what comes oem...but with natural camber those shouldnt be stickin out at all and shouldnt pose any problem
at all

I am currently not running a camber kit and never have.

The last time I had my alignment done was at Firestone and when they backed it off the rack my exhaust (muffler and piping) got scratched up on the concrete when they drove it off the lift.

I'll try to find somewhere to get an alignment again and let you know the results.

no offense bro but that has absolutely nothing to do with the OP's application. 195/60/15 is too big for a 2000 Si anyways so Im sure thats why you were rubbing

IIRC the OEM size is 195/60/15 which would be a 10mm overall diameter difference to 205/55/16. not a huge deal but still bigger than stock. also he has wheels that are wider and have a much lower offset than oem (20mm offset difference at least). IMO the wheels have the wrong offset causing the issue (making them stick out too far)

there are 2 oem sizes, one is 185/70/14 and the one you stated was the other one


and im running over a 25 mm offset diffrence and my rims are at least 2 inches wider than stock and i have no problems what so ever

to op...yea find a diffrent alignment shop...i see your in the middle of nowhere (no offence) and there arent gona be many smaller performance alignment shops around where you live...but just call around a couple places and ask if they have a low profile rack

also im going to suggest getting a pair of full coilovers instead of getting sleeves...how much is your budget

I'm not anywhere near being in the middle of nowhere. There just isn't any shops with a low profile rack. I'll still try and find one though.

I don't want sleeves. Full coilovers only. Budget is $1,000. If I can get something that works for cheaper that's fine too.

New wheels would be the cheapest route. This ,of course, depends on brand.

dont worry about the tire size that is a good size to run. factory stuff is too small anyways.
These guys telling you to run pizza cutters are probably the type that are only concerned about looks not performance.
The offset is probably the source of the problem. any reason you dont want to add a degree or two camber?

I personally like the size I have on the car. After all, it's on there, so I must have. lol Anyways, I do not have any problem with adding a little camber.

So the car will have negative camber on the front by a few degrees and how about the rear?

For a G youll be golden, yes there are other choices out there for $1000>, but i would recommend F&F type 2's

wouldnt people want smaller tires for performance unless they were off-roading...i remeber when i i went from a smaller tire/rim to a larger tire/rim my acceleration wasnt as quick as before (not much of a difference but noticeable on the butt dyno) and both rims weighed the same

just keep lowering until your tires dont rub...natural camber should be enough to keep you from rubbing also rolling of the fender should help

both the front and rear of the car will be fine at 2-4 degrees negative camber, just make sure your toe is bang on and you wont have any wear issues.

also, acceleration isn't the only aspect of performance, I assumed since the OP talked about high speed cornering that he was interested in all areas.
grip is directly proportional to contact patch.
