981 Boxster GTS Factory Suspension Geometry specifications

[Tricky54]

Does anyone have, or have a link to, the factory suspension geometry settings for a 981 Boxster GTS model specifically. This is for Normal road use. The GTS has 10mm lowered suspension as standard and the Hunter alignment system at my local tyre supplier only has the Base and S specs and not the GTS, so I need to supply the full GTS spec to them. Any suggestions on where I can find the factory specs?

All the Hunter systems I encountered when I had my two 981Ss had PASM -10mm as one of the optional settings. I think you'll find PASM-10 also applies to the GTS, but no doubt somebody will be along to confirm or contradict.

Agree with Brian, we have never had this problem at local tyre suppliers and the PASM setting was used for standard GTS suspension which is probably same as the S with PASM, there was of course another factory option of even lower suspension on the GTS so wouldn't be sure about that one.

I think on 981 there are only 3 different types of suspension (which correspond to wheel alignment settings), Standard (only available on Base and S models), PASM-10mm (option on Base and S, I think standard on GTS) or Sports-20mm (AKA X73) (optional on all, and sometimes retrofitted). The Sports -20mm is normal-type springs and dampers but lower and stiffer. It does not have PASM, so if you have PASM on any model it will be -10. That's what alignment guys typically select rather than the model of car.

That is correct

Hi Brian. Thanks for your reply which has solved the issue with the Hunters system. They have found the PASM option.

Hi Cliff. Thanks for your post but I've already been in touch with Steve and had a helpful reply. Subsequently I've been in touch with my tyre supplier, Trade Tyres of Shenstone, Staffordshire, who are top class, and they've now located the PASM -10 option under the 981 S options. Car booked in tomorrow for full check-up of settings.

Thanks for your confirmation too. Car booked for assessment tomorrow. See you Thursday with an update etc. Cheers.
