Jacking points......

[Guest]

I want to remove my wheels to give them a thorough clean and do not want to leave marks or even worse ,dents in the underbody .....

My ? is this ...if I use a standard trolley jack , where is the safest place to locate it and do I have to use anything to protect the floorpan....?

Hi taaffy,

Just got back from the Millenium Stadium after Wales lucky win ? My Bro in Law in Penarth will be on cloud 9 currently !

Anyway, on topic, the jacking points are easy to find under the car but have a good read of what the manual says about wheel removal first, its quite an operation to do it by the book.

I was going to do mine today as it happens but put myself off having read about all the things that could go wrong !

Good luck

Yves

Don't worry about it, the jacking points are sort of rectangular metal plates which protrude down below the plastic undertray arrangement.

Note, just make sure you have a reliable torque wrench and a sleeved socket, so you can tighten bolts properly (96 ftlbs) without scratching your wheels!

Last Saturday I fitted a set of wheel spacers to my C2S on the drive (took me 3 hours as the rear O/S wheel wouldn't come off!). Just make sure that the car is relatively level. If your jack plate/cup has a locater pin, all the better as the points have holes (approx 10mm ?) in them. Mine hasn't and bashing the rear tyre with a piece of 3 x 3 and a lump hammer required me to drop the car and realign the jack as it had slipped on the jacking point!!

BTW, not wanting to hijack your thread - but what a difference the spacer shims make to the steering feel! Instead of jiggling about at every pimple in the road, the steering has a slightly damped, more surefooted feel to it, which gives me much more confidence when pressing on. A great modification for under £50 !

Here is a shot which shows rear with O/S spacer in and N/S spacer out, the visual difference is only very subtle!

nsm3,

What size spacers did you go for ?

Sounds like a worthwhile tweak to me.

The largest you can fit to the 997 are 5mm. The OPC will sell you a set of 5mm for £229 and they include longer bolts. I got the shims from Porscheshop for £46 but they insist that the standard bolts are fine. I have done over 200 miles so far, including some serious cornering and the wheels are still on the car and all nuts are still torqued to 96 ftlbs, so I'm not sure what the longer bolts are for? Interestingly, you can fit 9mm spacers to the 996 (some models) and these do need longer bolts, so it might be a carry over from then? At the end of the day, of the 25mm of thread on the standard bolt, 15mm is in fresh air, right through the brake disc hub and only about 10mm of thread is actually in contact, so now I only have 9mm of thread collecting brake dust.

How come the Porscheshop ones are so cheap ?

Better hope you dont have any wheel/hub related issues, non 'Porsche' standard part fitted, warranty etc [&:]

What is the downside to fitting shims ? surely they would be standard if the improvement in steering feel comes so cheaply ?

If you go on the Porsche configurator, they are under wheels at £229 as a standard option, quoting "for front and rear axle, includes longer wheel bolts. Note: Includes security device. For Germany requires separate homologation".

They also list them under Tecquipment/wheels as "Wheel spacers create a wider track for enhanced stability and presence on the road. When fitted, the wheels run virtually flush with the body of the car."

Not sure how they could get away with any wheel bearing related warranty claims on that basis? The only difference with the Porscheshop shims is that they don't have the brake disc retaining screw holes in them, so to change the discs the shims would have to be prised off whilst still attached to the car. They are machined from "aircraft grade" aluminium and fit perfectly.

I will try to attach a decent piccy of them after fitting.

Front view

Rear view. I think the changes are only subtle - not exactly "Carlos Fandango" wheel extensions (If you can remember that old advert?)

Oh, also the Porscheshop sell the 9mm shims plus longer bolts for £124, so I can only imagine the additional £105 from the OPC is for the 2 extended brake disc retaining screws, and 4 locking bolts in lieu of 4 bolts plus a little bit on the side for themselves []

 

[YvesD]

Yep, I can feel my next mod coming on.

5mm spacers with some Slammin Eibach lowering Sportsprings to complete the look.

You dig ?

That thought had crossed my mind - another 10mm to get the benefit of the non-PASM version but keeping PASM.

Almost GT3 looking?

What is the cost, around £1,200?

Seems they might be far cheaper still http://www.europerformance.co.uk/pages/products/product_info.mhtml?id=445695 - Only £215 for the springs + £45 for the spacers. How much could an OPC possibly charge for fitting the springs????

Also the springs say -30mm so that is GT3 ride height...

Could well be a very cheap pair of mods indeed!

 

[nsm3]

If I am correct, isn't the GT3 20mm lower than a PASM C2S?

If so, the -30mm must be from a standard Carrera, or we would end up 10mm lower than the GT3, which I guess would be a step too far!!

I would only go down 10mm to the level of the LSD equipped S models anyway.

You could get the springs fitted by an independant to save on labour costs.

 

[Adam2S]

Yes :

Carrera std = 0mm
PASM = -10mm
Sports/LSD = -20mm
GT3 = -30mm

Eibach state -30mm so I agree and assume that therefore Eibach = GT3 ride height.

Very true re independent fitting, indeed I work only a few hundred yards from Strasse in Leeds so would be very easy for me to do. However given I have gone for the aerokit and all the horror stories of ground clearance problems with GT3 I think I would have to consider this upgrade with great care.

 

[YvesD]

What clearance problems are being reported by the GT3 Boys ?

The sticky down flexible plastic things under teh front valence and fron wheel arches look most vulnerable to me but should not touch down in normal conditions.

Extra care on the speed humps is the order of the day I think !

If my experience with Eibach on the M3 is anything to go by, the ride might actually improve. Anyone know if they make the standard springs ?

Apologies for the shocking spelling first time round !

RE ground clearance -
I have an aerokitted 997S, and I can assure you, even at std ride height, the damn front lip catches !
No so much on sped bumps, as long as you go slow, but it severely limits the approach angle. That normal looking incline into your drive from the road ? - it will catch.
I'm on my second chin spoiler after only 5 months of ownership.
20mm lower ? may look nice, but I can't really see it being practical.
I had a 996 with the aerokit & X74 suspension - that caught far less than the 997S with the aerokit, std PASM.

Taafy - design 911 do a jacking pad which slips over the head of your normal trolley jack. It has a locating peg in the middle, with a rubber cushioning pad around - perfect fit for the std jacking points.

Ouch[][][&:] - I nearly bought the body kit and went the sports suspension route on my C2S. I think I am relieved now I didn't. The rubber apron under the front spoiler on the basic C2S catches enough things............[]

 

[YvesD]

david,

Are we not talking at slightly cross purposes ?

Does the aerokit come with lower ride height or just a lower chin spoiler ?

The 997 actually has decent ground clearance at the very leading edge of the front apron, I think its actually better than my old 535d M Sport Beemer. Room to manouvre then.....

[david_yorkshire]

Yves - this was in response to the GT3 ride height / clearance query.

Yes, it has std ride height with the aerokit, hence my point about not going any lower !
With the Aerokit chin lip spoiler, the clearance diminishes very quickly !
