think i would rather fit slightly wider wheels...

 

Problem is, they're studs, you'd have to use longer studs and that involves taking off the callipers.

 

And hubs and drive shafts to hammer the originals out

 

don’t like messing about with spacers personally as it changes the suspension geometry

And helps chuck more cr?p down the side and onto those nice rear arches ?, but will definitely look better ?

Yes I had seen both videos, I was only ever thinking of about 10 mm each side as not to put to much strain on the suspension components.

 

I watched that vid. It looks like the spacers don't clear the original studs. Maybe just my eyes...

 

perhaps the back of the wheel has enough recess to allow for that if that's the case. its weird how we are all talking about car mods when we dont even have the car ! (most of us at least). i feel so sad.? I think I will stop. Should I enjoy the car as it is and all the hype before any mods

 

20 mm Spacers…

I measured...
Original studs front are 21,5 mm.
Original studs rear are 23,5 mm.
The "recess" on the BBS wheels are 3,5 mm (because of the outstanding ornaments).

So the front fits well, but (for me) the back "spacers" ought to be 22 (or 25mm) mm instead of 20 mm.
The 20 mm spacer might fit the rear - but the original studs touch or nearly touch the wheel…

Notice: (measured) front - space tire-sidewall to chassis outside is 20mm, rear is 25mm.
So if i would use spacers, i would do 20mm front - and 25mm rear...

So clearance behind the BBS wheels wont allow for a standard hub-centric spacer of 15mm will it? It would require fitting of longer studs instead - More effort than id like. Enkeis might be on the cards instead then...

 

I'm thinking the 20mm hub centric spacer should do the trick, front & rear. I'm planning to keep the 18s BBS wheels and probably change to a 235/40/18 tires later once stock PS4S are worn out. Drop + spacer and I'd probably call it a day! ?

Sounds like a great plan ?

 

Anyone using 15mm hubcentric spacer on long studs like this one? ?

I'm thinking if I'll go to 20mm or 15mm is fine

Looks so much better.

 

Never understood the obsession over wheel spacers, RS forum was/is the same..... that and excessive lowering.

 

Thanks for the inputs! My GRY won’t even see and feel dirt road. Probably uneven or harsh pavement from road works etc small pebbles here and there but that’s probably about it. Purely daily drive on street setup. Been running hubcentric spacers (good quality ones - project kics / eibach) for years without any issues. It’s just the little offset that I want since I’m sticking with the BBS wheels. I plan same size front and rear to keep some symmetry. I’ve done, 5/10/15/20 spacers depending on the wheel and tire setup ? All good

 

I have a Mini GP2. It is for sale. When it is sold, I am going to change the wheels and put off the spacers. E.g. 8.5x18, 35 offset. It is not the same like with 20mm spacers, but steeet legal in Switzerland.

 

The scrub radius change with a 15-20mm spacer is not going to be some monumental change which you notice a whole lot on the road or track. McPherson setups usually have a negative setup but that's a safety consideration as it acts similarly to neg toe by making the wheels want to find the straight ahead. So handy if you hit water on one side or have a puncture.

A bit more positive will add weight to the steering, you will have more bump steer when threshold braking and torque steer can be more prevalent in very powerful fwd cars.

There are just so many variables though. Fit tyres with stiffer sidewalls and you'll get more of a change than 10mm spacers.

There are also the benefits, track and roll centre improvements are good.

Have a think about how much this can change on stock cars. They are always offering different wheel sets as options or on various models with more poke

E.g. BMW are different because they use a double pivot, there is no straightforward king pin or scrub radius.

Usually more poke on factort wheel options is done with very little et change and by using wider larger wheels but even so, while it looks better, it does not always drive better. Because cars are developed on one set-up, than marketing adds their bling wheels and take a big surcharge. BMW has done more work lately on developing each optional chassi / wheel variant and it shows (before there used to one configuration that was best).

End of day, changing ET changes the intended (well engineered) handling of the GRY and I personally would never put (20mm ) spacers on this car (on the front). The GRY has lots of space for wider rims and that would be my recommendation if one wants to improve looks/stance (within reason), maybe with a small et change to 40 or so. 20mm spacer = et25 on stick rim and that has my engineering alarm bell ringing...

But to each their own, I just want to inform there may be consequences one perhaps did not consider before.

 

A 7mm spacer is a good option for those not wanting too greater impact on handling but wanting to improve the visual appearance. The H&R 7mm spacer can be fitted without changing wheel studs I believe? They tell me its also the spacer they haver fitted on the vehicle photographed for their lowering springs

Do you know for sure if the 7mm spacers are ok to fit with the standard stud?

I gave 6mm shaft nuts on my wheels so have a bit more thread engagement but am considering thin spacers

 

Likely that the static scrub radius at normal ride height will be in the range -4mm to -10mm as the front is a driven axle.
the worst scenario is adding spacers that neutralise (approx no scrub radius) this and the tyre behaviour becomes irratic due to inconsistent load.
going to positive scrub can be beneficial for track IMO but I’d preferably stick to OEM settings on the roads unless vanity wins out! ?

 

I've written it elsewhere but I'll add it here to, some real world experience on the subject. I have changed ET a lot on previous BMW M-cars that I've had. On my M2 I added 20mm spacers in the front with very good results. I mainly used it with wider wheels which needed 20mm spacers to get back to stock ET. But I also ran stock width wheels during winter with the ET lowered 20mm with these spacers on the car which worked without any tramlining added or any other downside.

Now on to GRY. With Michelin CUP2 Connect in stock size 225/40-18 on the original 8x18 ET45 BBS and these same tyres on after market 8x18 ET35 (that also are much heavier) I got:

- A clear increase of tramlining
- Heavier steering, especially noticeable around center for smaller inputs

Late edit: A lot might also have to do with the rims that are crazy heavy ?

 

8,5x18, 9x18 or 9,5x18 with wider tires but nearly same offset (about ET 40-45) is much better to drive and gives you more feedback than 8x18 with standard tire size and more offset (like ET 30-35) or spacers.
8,5x - 9x - or 9,5x18 with even 255/35R18 and OFFSET 40 fits perfect in wheel well, even with front camber -3°...enough space to spring-leg plate...

For those looking for a pair of 15mm hubcentric wheelspacer with 10 long studs included (hub bore 60.1, PCD 5x114, stud bolts 12x1.5) this should be the part number. (S90-6-15-034) I'm sticking with Eibach spacers since I'll be installing Eibach ProKit springs also. This comes from the Toyota Camry/Lexus IS with the exact specs for the Toyota GR Yaris

 

I got this ones made here in Spain. 20mm. Hopefully next week will be on along with Eibachs!

 

This is from KSP in Japan (20 mm front and 25 mm back) Looks much better, also waiting for the Eibachs to arrive

 

Anyone fitted 15mm spacers?

 

Doing this setup. Looks like the spacers will come here first before the car

 

TBL Tuning
You won't find it in the shop. You have to write them an email. They are located next to my hometown.

 

Where did you get these from?

you can get them from Tarmac sportz, they've got some in right now

How did you get on with this setup? Any rubbing when lowered?

 

No problem with this setup. Runs perfect.
