Just installed my Progress coilovers today. Want to know if any of you guys rub with severe drops and anyone need to roll their front fenders? I can't find even ground to get the same 2 measurements but it's about 25.5" front and 26.25" rear center of fender to the ground. Front rubs a lot and the rears on occassion. I figured I'd only need to roll the rears but I guess I have to do the fronts as well now. 245/35 40ET offset. I'll likely raise the front up a little in addition but I didn't expect an extra 1/2" drop to make such a difference.

Guys like Poowill and VIP Maxima if you could chime in...

since u are talking about rolling the fenders then im assuming that you rub when you bounce.i dont have this issue but my wheels rub slightly when i turn the steering wheel all the way to either direction, causing a higher turning radius. but thats because i am running -3 camber on the front. the back has never had any problems with rubbing tho. i also run 245/35. either you are too low or perhaps the spring rate is too soft and you rub when you bounce. how is ur wheel gap in the front? can you fit a fingure ?


btw, you might be hitting the bumpstops thinking that you are rubbing... i experience this non stop. post some pics

I'm at 25.25" in front and I also rub on dips and hard cornering. Springs are preloaded and the shocks are set to about 65% stiffness to limit front suspension travel. I have less than an inch to travel before the little screw securing the fenderwell splash guard rubs the tires. Wheels are cambered in all the way using the camber plates and tires are 235/45 on 8" +31 offset wheel.

If I got smaller tires (225) or less aggressive offset, there would be no rubbing problems. From your cardomain it looks like you're running 245's on 8.5" +40 offset wheels, which makes the tire fitment pretty aggressive. I bet if you ran 235 tires it wouldn't ever rub again. I think 1fstmax was rubbing slightly too with 245's on similar size wheels and when he tried some 235's the rubbing went away.

i run the same tire size as him 245/35/19 yet i have no problems. im assuming our offset should be pretty close too (i dont know mine but i think it was 38 since mine are 19x8 & his 19x8.5). but this could very well still be his problem

btw that screw in the fender wont hit your tire cuz when u hit a bump, the suspension curves in, it doesnt go up and down in a straight line. feel free to dump it haha

25" range ppfffft...

i was in the 24" range and i still might be.

You will have to remove the two screws in the fender well so the tires dont rub it (yes the tire does rub the screws). Also roll your fenders and you will be able to get more room for the tires in the back. negative camber helps.

i brought my car to the mechanic for a clutch job and he raised my car 1/2" and didnt tell me about it. he said it was too low. hahahaha i have 245/40-18 tires and they would rub in a straight line.

You're hitting your bumpstops???? Did you lower it by loosening the spring perches or the strut body??? A big reason to go with (most) coilovers is to eliminate the suspension travel/bumpstop problem. The coilover shock body is threaded so when you lower and raise your car you don't pre-compress the shock and you don't lose suspension travel because the entire length of the coilover changes.

VIP Maxima

the spring are still under load. i lowered it via the shock body. but i still hit the bumpstops when taking turns. or when hitting big potholes on highway

maxima985spd

Pr00f? Or do you just hear a thud?

I'm definitely not hitting the bumpstops. One of the reasons I got coilovers was so I wasn't banging on the bumpstops (like with my S-Tech's). I would definitely recognize the feeling.

Judging from the rub marks on the front it's likely that camber correction or smaller diameter tire would solve it. I haven't gotten an alignment yet but I was running camber within spec with my last alignment (-.8) don't mind running aggressive camber but not too crazy about the tire wear and the fact that the rear camber can't be adjusted. Looks kind of silly having major negative camber in the front only..I don't plan on switching up tires though about 11k on them..

I'll snap some pics in the day...

As stated above, you can roll the rear fenders. I had mine cut because they were in danger of cutting into my 245/45/18 on 35ET... my front still hit the screw head.... maybe i'll take each top screw off in the fenderwell. I'm running H-Techs.

VIP Maxima

i hear multiple thuds as i bounce up and down......


bonka- more than likely its your tire size due to the offset. i say roll the fenders and it should go away. progress coilovers still should be way more stiff than your s tech to prevent you from hitting the bumpstops

your rubber is too wide for your drop.. try opting for some 225/40 instead..
my rears do not rub.. the front only on dips, but then again,I could stiffen up the front and problem solved..

oh yeah, I did NOT roll my fenders

Here are some pics I took after the gym this morning...

I'm going to adjust the passenger rear a little to even it up with the other side...making a little noise anyways...

What kind of wheels are those? They are very nice.

Drop that @ss down hahaha.. I'd say go with a smaller tire man, thats what we do on the drift rims with crazy lip. Usually dont have to roll fenders, but w/e maybe that's you're solution if you wanna keep more rubber on the road (and better looks). I mean that's not that low anyways.

This does however make me a little uneasy as I'm getting some staggered Z rims (the 5-spoke ones) and they're pretty wide with a decent offset and I'm sure I'll run into EXACTLY the same problem at that point in time which isn't far down the road.

VIP Maxima

hard to say, u have so much room. i am dropped even lower than that with no issues !

maxima985spd

your rubbing????? you have so much room there. I am a lot lower and I rub sometimes.

VIP Maxima

yea i cant understand how he is rubbing either. maybe his springs are too soft?

maxima985spd

yea thats the only thing i can think of

Digitized

either his tire size is wrong/ offset is wrong or shock is set on too soft...

like many mentionned, a few of us are even lower and no rubbing issues..
in the fron, I can perhaps fit 1 finger, and I rub only when road dips( front is set on medium soft..) and the rear, I and tucking, set on stiff and no rubbing..

I am running 18x7.5" rims with 225/40R18 tires..

something is not right with your set up?

VIP Maxima

with that drop, i highly doubt offset and tire size has anything to do with rubbing since he has PLENTY of room.

take off your wheels and make sure your springs are under preload. you are doing something wrong. you can easily go another 1" without rubbing.

True, I was just merely trying to cover all possible aspects..
but if he rubs while he has like 1 inch wheel gap, something def isn't right...

I wonder is he on super soft for shock settings?

My coilovers are height adjustable only. 8/6kg springs. It's fine. It's likely my camber since most of you guys are on KSports/D2s and many of you seem to be maxxing your camber out whereas I'm very conservative. I'm going to leave this as it is for a few more days so everything settles and I'll adjust it one last time before I get the fenders rolled and the alignment done.

but you are not dropped that much, therefore, camber shouldn't be an issue.
I myslef have -0.5 camber in the dront.. and the rear is the same if I remember...

Hmm, maybe your shocks are too soft.. that's the only way I would see how the front rubs.. but the rear.. I dunno

VIP Maxima

that is not true sir. when my camber was set at 0. i still had no problems with rubbing, in fact, i had no rubbing AT ALL. i started to rub when i went to -3 camber. now it rubs when steering wheel is fully turned.

check your spring and shock carefully, make sure they are set right.

I have 18x7.5 ET40 235/40/18 rubber. I was rubbing bad in the front with a 1 degree camber. I rolled the rear for spacers and set the front camber to -1.5 and I have no rubbing issues at all. Make sure you get an alignment, its the most important suspension mod you can do. Doesn't matter how much you put into rims/rubber and struts if you have a bad alignment its a waste of time.

my alignment setting are as follows.

Front: -1.5 camber 0 toe
rear: +.5 camber 0 toe
