Size of wheel spacers on staggered turbines?

[Lodo1000]

I’m having trouble getting 20mm spacers from Motorsport-tech to for correctly on the rear with 21 arachnids. I’m a little baffled as I haven’t seen anyone else suggest they have had an issue.

The wheels have two deep channels and 3 shallow ones. As you can see in the photo, the three shallow channels are preventing the wheel from seating cleanly against the spacers. This creates an immediate unbalanced wheel rotation.

Am I doing something wrong here?

Looks like you have two options for a solution here:

1. Drill the three areas of contact on the hub of your wheel so you have clearance.
2. Grind the tapered area on the OEM threads so you have clearance for the hub.

I would recommend option 2 to preserve the integrity of the Arachnid wheel.

Yes, not thrilled with grinding either but agree those are the options.

What I’d like to know is if my arachnids are irregular in terms of these deep and shallow channels. I don’t hear anyone else struggling with the fitment. Then again, might not be something people want to talk about ?!?

Very strange, measure the length of your wheel studs (highly unlikely but they could be too long/extended ones

Grinding 2mm off the tapered tips will not touch the threads ... easy solution

A pic is worth a thousand words... Forgot the stock studs had the rounded ends, so thumbs-up @FlatSix911.

I ordered 5mm spacers for the rear as I rub on the inside of the tire. Will the lug nuts I use now fit or do I need new lug nuts? 5mm doesn't seem like much and think it might be ok?

 

[FlatSix911]

Check for full engagement of the threads ... 10 full turns of the lug nuts are the standard.

Ok, thanks for the info Flatsix.

just installed 20mm spacers all around yesterday. had to cut the guide post off three studs on each wheel to accommodate the spacers as OP noted the arachnids have 3 shallow and 2 deep recessed on each wheel. quick and easy with a dremel and cutting wheel. no threads are removed in the process, so it doesn't compromise integrity in any way.

drove 75 miles and rechecked torque of the nuts on the spacers, all were still at spec'd 129 torque . i have a p100d and did several launches to stress them as well.

very happy with the stance.

FAKE NEWS!! lol, sorry couldn't resist.

but it honestly is unfounded paranoia IMO, to each his own. have run spacers on many cars, including my 911 which had porsche OEM spacers, never an issue.

Did you have the same issue with the front also or just the rears?

Looks great, Can you post some pics from the side? I want to see how flush they are with your wheels. I don't know if I should get 20mm spacers front and rear or go 25 front and 20 rear.

Thanks in advance!

here you go, hope this helps. you probably could fit 25, but i personally think the 20mm is fine.

​

So if I order a wider spacer, say 22mm instead of 20mm, would that eliminate the need to grind off that extra 2mm from the tapered end of the studs?

Correct.

another q on this topic... i have a staggered setup on my p85, with 265's on the back.

i am putting on 275's in the coming weeks..

would a 10mm spacer on the back make any difference in the look of the ride? Can i just put 10mm on the back and leave the front stock?

I run staggered Arachnids in the summer months and a 10mm spacer will push the wheels out almost flush with the fender.
