lowering a 997
Discussion
Hi all.
im thinking of lowering my 997 Carrera 2s,
iv been doing some reading and it seems techart or H&R lowering springs maybe the way forward,
I was also reading that the cars with PASM are already 10mm lower, and I didnt really understand if people were saing for that reason you can get away with spring 10mm less or not, I have PASM and the sports button so don't know if its always 10mm lower or in one of the two settings,
so I was wondering if anyone had lowered theres and how did they get on, what they used and what the ride was like, as is my car is fine, but with the sports button pressed its a very bumpy ride, and any pictures would be great, I enclose o phot of how id like mine to look.
thanks.

I used the H&R springs on my 997.2 GTS and they were great. Lowering of around -15mm, much better ride quality and improved handling, better visual look and no downsides.
Pics of car standard height (original GTS wheels) and one with H&R springs with GT3 RS wheels.
that looks nice in both pictures, im guessing the GTS is a bit lower to start with compared to mine?Pics of car standard height (original GTS wheels) and one with H&R springs with GT3 RS wheels.

I have driven various lowered 997s (on coilovers) and they all had terrible bump steer! I'd be cautious of lowering too much, might be worth discussing with someone like Centre Gravity or other Porsche tuning specialists.....
I'm doubtful it was bumpsteer in the true sense of the word. More likely someone fitted the coilovers and dropped the ride heights too far, or they didn't reset the toe, camber and caster after the fitment of the coilovers ? Result ? A car that feels like it's got bad bumpsteer issues, but is actually suffering from poorly adjusted geometry. From your description, I suspect the lowered cars you drove most likely had at best parallel front toe settings (or more likely toeing out) along with excessive camber on both the front and rear wheels.

Thanks for the article, it would have been useful during my dissertation on Porsche suspension kinematics.

Have had Eibach pro-kit springs on our 997 Carrera S for some years now. -30mm I think. To my eyes the car looks 'factory' rather than 'stanced' - until, that is, you park it next to a standard car which then looks like it has skyscraper springs. Enough adjustment in the standard suspension hardware to achieve factory geo too, so there's no unnecessary tyre wear. She's a little bumpy on our (very poor) local Lancashire pot-holed roads, but the smoother the surface, the better she runs.
Oh, no painted areas of the front bumper scrape either, just the 'blade' spoiler underneath the front occasionally catches speed humps etc.

I had the same H&R springs on my GTS as Chris at ABP, I did have the geo adjusted at the same time and had no issues with bump steer, harshness or grounding out. The best change to ride quality was changing out the OEM Bridgestones to Cup 2's. The car went onto ferries and Eurotunnel (with care) without issues.
I think I still have the springs knocking around somewhere if someone wants a second hand set.

looks spot on that mateOh, no painted areas of the front bumper scrape either, just the 'blade' spoiler underneath the front occasionally catches speed humps etc.
