981 Spacers

[Arte-et-Marte]

I have been given 2 sets of brand new 18mm spacers (Eibach) which will fit my 981 (20" 235 and 265 respective)
These are bolt on as opposed to through so there are no existing wheel bolt changes required...Just wondering if anyone has any fitted and has experienced any issues?

I don't recommend this.

I would be very wary of fitting 18mm spacers to your 981 Boxster, especially the bolt-on type. Increasing the track on each axle by a total of 36mm is too much in my opinion. The extra leverage on the wheel bearings, together with possible wheel arch rubbing, balancing, and handling issues make this a no-go in my opinion.

Although Eibach are a reputable brand I'd go for their solid spacers kit with extended bolts with a maximum of 9mm of spacer thickness.

I have extensive experience with wheel spacers, the solid extended bolt versions, when previously campaigning my 987 Cayman R in competitive motorsport events. The 9mm spacers with extended bolts, widened the track by 18mm in total and I had absolutely no issues at all.

Hope this helps.

Thanks very much for your advice Brian

I did have a gut feeling that it may be a bridge too far!!

Much appreciated

You're welcome Rich.

Wheel spacers have tangible benefits on 987 and 981 Boxsters and Caymans. 5mm, 6mm, and 9mm with extended wheel bolts are fine. The 6mm and 9mm spacers I used on my 987 CR had wheel centre hub flanges to locate the road wheel. I tried all the combinations and found 6mm spacers on the front, and 9mm spacers on the rear worked best. It also had aesthetic benefits giving my CR a more purposeful stance.

My 718 CS does not require spacers as it has a wider track as standard and the 8.5" and 10.5" alloys fill the wheel arches adequately already.

I ran the same backwards as having a wider front track helped turn in. some thing Porsche did on the standard 981 over the 987 for real, ie. increased front track to aid turn in on the 981 car over the 987, having wider spacers on the rear of a 987 would cause the car to push even more...… one can go 10mm upfront and 5mm rear and that makes the 987 more 981 ish and improves turn in and over all track of course. Spyder wheels also gave more track than the normal wheels.

My thanks once again Brian...Pretty sure you've saved me some potential heartbreak over time!!

Sorry to dig up an old thread here but an I ok to fit spacers onto a Boxster S 981 with 20" wheels. The porsche tequipment page says 18" alloys only. What would the problem be on larger wheels, clearance seems sufficient for 5mm or 7mm spacers. If I go for the Eibach kit, where do I get suitable bolts as I cannot see them listed ?

Any other recommendations.

They're not approved for 20" on 981's but there is no fitting issue with them. I've had them on mine for around 3 years. Getting a warranty with them on can be an issue with some OPC's, but not others.

Can I ask what kit you fitted Mr PG ? There is no warranty to worry about [8D]

 

[mr pg]

Porsche 5mm spacers plus longer bolts.

Cheers mr pg, I will speak to my OPC nicely for some pricing !
