Hi

I'm a french guy and i speak english like a goat... sorry...

I have a Cayman R Pdk.

I use it for track days 15-20 time per year since 2013.

I use only tires MICHELIN PS CUP 2 (235/265 R19)
Pagid RS29 Break pads
Reinforced brake hoses
Motul RBF 600 fluid breaks

The car is completely stock ... exhaust, dampers ... 100% Stock

The camber settings are those made by Porsche in factory before delivery of the car.

Tire wear is very bad on the track. I put with pressure hot 2.0 / 2.1 and the tires wear is on the outside. I am forced to change tires because the outer sides are on the scrap whereas everything else is not worn.

I search to get information about the camber that I must put on front and rear. I only use this car on that road to get to the track, but I do not want her to be dangerous on the road with a too aggressive camber.

I also want to know if it is possible to lower the car by keeping the dampers and springs origins?
And if so what is the recommended height in inches for track use.

What advice can you give me ?

Thk for your help.

Welcome. Unfortunately with the stock parts most can only get a little over 1 deg neg camber. I had GT3 lower control arms installed in the front on my R and needed about 10mm of shims each side to get to neg 2 deg. Tire wear is much improved but I still wear the outer edges. At 2 deg neg it's ok on the street but I didn't want to go more since I drive to and from the track also. You can search on LCAs and there have been some other threads on this mod. I used Porsche parts but there are aftermarket parts too. Best of luck

Oh, also, the ride height is not adjustable with the stock R suspension.

You cannot lower the car using the original springs and dampers. You need more negative camber in the front and can get it using camber plates or adjustable lower control arms. I recommend the Porsche GT3 lower control arm. Aggressive camber is not dangerous but could cause faster tire wear on the inside of the tire. I ran -2.5 F and -2.0 R camber for years on the street with no issues. Your English is better then my French.

2° front is a good compromise, 2°30' doable and works well on the track. As others said, GT3 lower control arms are the way to go. Would not do 2° on the rear axle, the car gets very aggressive, difficult to control (and that statement was made by a professional race driver in the drivers seat of my car), 1°30' give you a more controllable break away and a more playful car. You might want to test it, investment even with a Porsche shop is not too high (<€200 to get the alignment redone).

Thanks for your informations and advices.

I didnt know at all that it is not possible to adjust the height with the stock dampers.

I knew we could mount the LCAs GT3 but i cant pay this season. Parts are expensive and its very expensive for assembly too.

If I decide to invest so much money next season, I change at the same time LCAs (R -> GT3), dampers by BILSTEIN PSS9 and brake calipers (R -> GT3). But for now this isnt possible this year (money, money ... grrr)

Sven76 @: In southern France, an official Porsche shop want 350€ for a camber ... and an unofficial shop want 250€. Also I would not have to pay several times ... I wish rather keep my money to come again this year for driving on the Nordschleife and Spa ;)

Crazy prices, probably too many rich people who don't care running around in your hood. Over here, I have 3 dealers within 15 minute drive, probably 6 official dealers within 30 minutes and at least as many independent but Porsche specialised shops. Competition keeps them sober.

if you go down the route of a full fledged suspension, you might not need the GT3 lower control arms, I was told with a KW suspension I would not need them. But I like the softer Cayman R suspension, so got the lower control arms instead. Check with a reputable shop to make sure you only buy what is necessary.
