i currently have 16x7 Rota slipstreams (offset +40) with 205/50R16 on my MCS lowered on Eibach springs and they are rubbing at the rear whenever the car dips

i have h-sport rear control arms arriving, will these solve the rubbing? or should i just have the flares shaved a little?

 

your control arms can definitely help to provide more neg camber for
clearance.... for dressup purposes that's fine, but for performance,
you should probably not alter the neg camber just for clearance...which
means you should probably shave off just a smidge of the rear arch.

 

205/50-16 tires are OK for tire diameter compared to stock.

16x7 rims are wider than stock and you have too little offset at +40mm, probably +42 is the limit for you. +45 would have been better.

5mm spacer would help as long as your bolts or studs are long enough to lock the wheels on the hub.

H-sport springs are 1 inch drop front and rear so I doubt that it would be any less drop than your Eibachs.

Rear camber might help if you made it more negative. Stick to about -1.5 to -1.8 degrees.

It's always good to shave a little plastic from the inner rear portion of the wheel arches. Use a dremmel tool to make it easy. You don't need to take off that much. Put your finger on the inner plastic of the upper rear arches for the back wheels and feel where it is rubbing and start there.

Another idea is to switch to Koni yellow shocks and adjust the dampening. If you old stock shocks are worn out then they are too soft and that is resulting in some rubbing. If the Eibachs have been on for over one year the stock shocks could be worn out.

 

minihune - i think the 5mm spacers will shatter the rear arch off the
quarter panel after hitting a dip.... (going the wrong way)

 

I had 215/50/16 on 16x7 ET42 and Koni springs (fully tucked in the rear). The LR would rub slightly over dips....never audibly. I'd see a bit of plastic on the tire from friction.....just a thin layer. Never enough to worry about. Frankly, I'm shocked a 205 rubs even on ET40. Maybe it's a 7.5" wheel?

 

my comps that were 16x7.5" running 205/50/16 never rubbed (GS-D3's)
there was about 3mm clearance.

 

what offset?

I'm running h-sport camber links but to dial camber out from lowering, which is why I'm scratching my head here

 

oh yah, forgot to post... it was +43mm.

i dont mind the rear camber on this car from the h-sports. i can
make the rear break loose with throttle inputs on demand.

are you dialing out for cosmetic reasons?

 

no, performance reasons. It was up over -2.0. I brought it back to -1.5 for more stability.

 

yah, seems like these h-sports drop more/less on different cars.
could be the gross weight with the driver and passengers too though.

 

I've got Bilstein PSS9's, so I was able to set my ride height. The Koni springs I had sat much lower....too low in the rear. I still don't get how 205/50's rub.

 

Woops. more offset I mean.

No spacers- that would push the wheel outward and into the wheel arch plastic trim.

Yes, check that these are 16x7 and not wider rims. And check the markings on the inside of the wheel for the offset.

Probably rear negative camber is too positive to help with clearance.

 

just checked: the rims have +40 offset, 16x7

i actually got the control arms so as to not to wear out the tires too much. also i'm under the impression that negative camber in the rear results in understeer (am i right on this?) so the control arms are still going on. after that, i think i will definitely have to shave off some of the inner flare

on the condition of the shocks & springs, the springs are about 1,500+++kms old, the car has just over 10,000kms on it so i'm assuming that the shocks are still fresh. you would not believe the dips that we have on our roads here in the philippines

 

especially on springs....I'm confused

40 offset is totally fine with a 7 inch wide wheel.

 

I have the same Rota Slipstreams (16x7) with a 40mm off set as you run. I run Nitto Neo gens (205x50x16) tires. I use Alta lower control arms and run with M7 springs (1.3 drop). I have never had any rubbing with my set up and have run on some very aggressive roads with lot's of major dips,still no rubbing. I'll bet it will go away when you change out the lower control arms and the brand of tire might play into the rubbing a bit.

 

Advan AD07's? Maybe they run wide

 

i run hankook Z214 205/50-16 on the track with 40 et too, and i dont hear any rubbing from the rear...

 

Each tire will vary a bit with each model and manufacturer for tread width, sectional width and tire diameter for a given tire size. In addition the tread shoulders can sometimes be very square or relatively rounded.

Rubbing is increased and clearance is decreased with-
wider tread or sectional width
taller tire diameter
wider shoulder tread design

Then there are small variances with each suspension setup even with identical upgrades and a range of alignments that might help or reduce clearance.

205/50-16 is not a troublesome size for MINI tires.

 

I hope that was for the general public and not me (since you quoted me) or you just wasted a bunch of energy punching the keyboard

 

No, you just had a specific tire to reference.

In 205/50-16 size:

Yokohama ADVAN Neova AD07 only come in 175/55-16 for 16" wheels, not a suitable tire for the MINI

Nitto NeoGen VR

Continental ContiSportContact 2 section width 8.4", tread width N/A, tire diameter 24.4", Max Performance summer tire
Goodyear Eagle F1 GS-D3 section width 8.4", tread width 7.2", tire diameter 24.1", Max Performance summer tire
Hankook Ventus Rs2 Z212 section width 8.3", tread width 7.2", tire diameter 24.1", Max Performance summer tire

Hankook Ventus Z214 section width 8.3", tread width 7.7", tire diameter 24.0", Competition tire

 

the OP has that tire listed in his sig. Perhaps that's his issue and yes, I'm well aware each size and model varies.

 

I'm running 16 X7 OZ Ultraleggeras - 37 et - with 205/50/16 General Exclaims and have not experienced any rubbing , even during very aggressive cornering.
