Hi Guys,

Just wanted your opinion on an issue i am having.

I just installed new HRE FF'01s (stock offsets from HRE) on the car (previously had the stock 18s)

Front- 245/35/19
Rear - 275/30/19

The car is currently dropped 1.5 inches on H&R suspension and now the car is rubbing really badly. I expected this but what is the best way to fix this without having to raise the car back up too much? My shop has already trimmed the fenders down a bit, and raised the car back up about .5 of an inch yet the car still rubs on the slightest dip.

Do i have to add some negative camber to the car? Maybe anywhere from -1 to -2 negative camber so that the tire goes up into the fender rather than hitting it?

What do others with 19 inch rims, 275s in the rear and lowered cars do to avoid this? Any feedback is sincerely appreciated, thanks guys!

First off, the proper offset would have cured that, what are those stock offsets? But for the rear tires, unless you can switch to 265s (not sure if that's an option), the next course would be to add - camber. I would think you can talk this out with HRE since they are close to you. Chances are the rub is slight, it just sounds bad since it's bever been there before. is the rub on the outer sidewall? or is it hitting close to the top of the tire where the thread pattern is? if the latter, than you have bigger issues here.

Yea the rub is slight and on the outer wall of the tire, not the top.

HRE's recommendation on the offset they have for the rim was to go with 255's but with the amount of power the car has i wanted to go with 275s (i currently had 265s and wanted to try 275). Im going back to my shop tomorrow and they are going to try a slight negative camber and if needed, i may just go back down to 265.

The only problem i see with not fixing the current rubbing is that if i carry passengers, my hope is that the rubbing doesnt become constant with too much weight. Seems like i cant have everything i want

- lower car
- wider tire
- no rubbing with passengers

cant have the cake and eat it i guess

I am about to buy these wheels for my C63. What size and offset did you get 19*8.5/19*9.5, 43mm/47mm offset?

Can you post a pic?

KINGPIN 007

Sure, ill post the pic first thing tomorrow morning (its night time over here right now and i dont have any existing pics, just got the car back). I have to double check the offsets, will let you know tomorrow as well. They do look quite nice though

Conv_GSDriver

yes i'm curious about the offsets, those should be stamped on the inside of the rim, outer lip edge. If it is slight, the 265s should do it, but get some people on the back after you install the 265s. as far as putting power to the ground, get a tire with a sticky compound. Even with 255s, with enough stickyness and suspension to keep it planted, you will be ok.

HRE FFs don't come in custom offsets. They all come in 9.5 ET45.

You will need to run 255s to be 100% safe, you might get away with some brand 265s, but it will come down to luck. 275s you will have no chance, especially considering you are lowered.

To give you an example. Stock 19 multispokes are 19x9 ET54. Some people have added 10mm spacers to make it 19x9 ET44, this is 2mm more outer clearance than the 19x9.5 ET45 (HRE FlowForms).

Some people have run the multispokes with a 10mm spacer and 265s with no problems being lowered, some people have run the 10mm spacer with 265s and rubbing, one example I remember was the 19x9 ET54 multispokes, 10mm spacer (19x9 ET44) and Michelin PSS 265s were rubbing.

Hope this helps.

Sounds good. Interested in seeing them.

Are you on adjustable H&R coilovers or just lowering springs?


If you're on coilovers, you may want to crank them up firmer so you don't get so much rebound as well, as first step.


Otherwise ET45 with a 275 on a 9.5 rear will rub, when dropped 1.5"

I'd say play with your adjustments on the h&r's. If it's springs, then the drop would only be .75, also check the rear spring pads....there are a couple of different sizes to them as well, I'm on the thickest set which I believe are 17mm....my original ones were 14mm so I got a bit more clearance. My offset on mine is aggressive at 19x10 et 45 on 265pss lowered on h&r springs (.75 drop) and I get rubbing with 4 average sized guys in my car

If adjusting camber doesn't work, go back to 265.. also you can check your clearance by using a straight edge(ruler) on the outer most part of your tire, and see where it would touch on the fender edge.

Your going to rub with a 275 wide tire in the rear.


I am running much more aggressive offsets on my HRE FF01's and rub very very little on the passenger rear side (Battery side)






I am running 19 x 8.5 upfront 30 Offset and 19 x 9.5 rear with a 44 offset. But I stuck with 255 wide tires in the rear and 225 wide in the front. Suggest you drop down to 265's and see if that would work. I can tell you I will probably be able to squeeze in a 265 in the rear next time around. But tire choices with the appropriate sidewall profile is key to get it to fit.


I am lowered on H&R Coil Overs as well.

Kriston

You know what you are talking about, this is why I stuck with a 255 tire first time around on my set. The Advan Sports are very sticky tires and I have no problems hooking.


But I do agree it doesn't hurt to have a bit more rubber in the rear!

Thank you for all the feedback guys, I really appreciate it

Yea im going to drop back down to 265 in the rear. MY front doesnt rub or have any issues so is it okay for me to stick with 245s in the front if i go with 265s in the rear? Or should i drop the fronts back down to 235s as well?

My fenders have already been shaved down so if i drop a tire size, i think i should have just enough room to avoid the rubbing altogether and can leave the car at the current height.

If you are on coilovers adjust them in order not to rubb. 1.5" is probably too low. On KW V3 the max height is 1.2" according to specs.
On H&R springs you should be at .75 max as already mentioned. And with this settings you should rub only on big bumps with 275 with 9.5x19 ET45.

So adjust your coilovers or downsize your rear tires.

This^^^^with a 1.5 drop, that car must be slammed hard. my .75 drop is good and I can barely get a finger in there

I have the 19" FF01's installed on stock suspension. If i have 4 people in the car I can hear it rub in the passenger rear when going over a bump in the freeway. 265's in the rear

KINGPIN 007

So ive decided to change the tires, im going to go with the following

Michelin pilot super sports

front - 235/35/19
rear - 255/30/19

Since michelin make their tires a bit wider than normal that should allow me to still have a nice stance/look and not rub as much. Also my H&R suspension is adjustable so we will be tweaking that as well. I dont mind if the car rubs while on a dip, i just dont want it to rub on a constant basis with 3-4 passengers.

Once again, i really appreciate all the feedback guys, you really helped me out, Ill post finished pics real soon!
