Stock GT3 doesn't have helper spring, it is already an H&R. Play with your swaybar already.

Michelin Cup is for Track only, undrivable in the rain.

Pirelli PZero Corsa, good for track and everyday. Little less grip on track than Cup.

Pirelli PZero, good for everyday, less than Corsa on track.

Pirelli Nero: bad

Pirelli Rosso: bad

Bridgestone RE050: Good for everyday, less than PZero on track.

I use Corsa for everyday and it is a good compromise. I heard the new Cup+ is not bad but I am waiting to test the new Pirelli Tropheo.

I've done it on the Front, it will fit perfectly but you need 997 TT disk on the front. 996 GT3 Cup disk didn't fit. I have the caliper for the rear but I will need to change the handbrake jaws too.

Hello Everyone,

I've also made the changes: X51 Airbox, cuttings etc ... I saw a few post on adapting the X51 TB. It will not fit the standard Plenum T. And I can confirm it now. I manage to send my RSS IPD Plenum back so they can adapt the X51 TB. Apparently Greg (RSS) confirms that it is possible and will be in their catalog soon. Of course, you need to get the ECU Remap for the extra intake air. The MAF diameter between the stock an X51 airbox is the same so the flow will increase with the mods and can be out of range.

Cheers.

Hello RonCT,

I have the 997 Cup Control Arm on the front, what is the maximum camber for stock 997S. Because I am thinking to replace the rear one too. Thanks.

This is weird, I just install mine without a problem, you just need to replace all the bushing: front and rear because not the same diameter. I setup mine on Front: 2 and Rear:2 Same than GT3 but had to change to Rear:1 because of Tail Happy. If I got wider tyres I will go back to 2. I will try to send you a picture of the GT3 Rear Sway on my 997S. About your tail happy car, it is the contrary, if you rear is stiffer, it will increase this effect. You have to soften the back. Also very important, tyres pressures, you might have too much pressure on the rear. To setup the sway bar you do not need to drive like crazy, even at slow speed you can feel it. At the moment, my car is very neutral I do not have any problem slowing down from 220km/h to 70km/h in 100m and taking a 90 degree turn. Full brake in the straight and a sligh breaking during the turn just to put grip on the front wheel.

Many thanks guys, I was just a bit scared when my oil temperature rise up to 115°C during track (Paul-Ricard Circuit) and when back normal during the 30mn break. I will be there on the 18th and it will be very hot on tracks ... PS: Have a look on my site: http://www.youtube.com/mapounet

Cheers.

You mean for Track Racing?

1 - PASM on Sport Mode

2 - PSM ON for beginning and OFF later but depend of the track type really

3 - Tyres: Recommend OEM High (F2.3 bar, R3.0 bar) and deflate it every 30mn because the tyres pressure can go up to 3.8 bar easy. then you car start to slide! :D

Hello Everyone,

Just need some advise on oil for Track. I believe 0W40 and 5W40 is not the right one. 0W40 is good for cold country, 5W40 is better for countries like us. But why a lot of people is using Castrol RS 10W60 for track ... Answer: the oil is thicker and will stay longer on the upper of the engine, better lubrification and less break down! Any experience? Thanks.

997 GT3 Wheels will fit 997 and 997S Narrowbody, true.

Rear:

997S: 11Jx19 ET67

GT3: 12Jx19 ET68

GT3RS: 12Jx19 ET51

Be carefull anyway ...

Yeah, yeah, we have 98 here in France and 102 on the racing track ... Unplug your battery and all the procedure for ECU recalibration. To be honest no worth the spending.

Need a XZN 12 Tool to remove the old wheel and a small rod to remove airbag, don't forget to unplug battery first for at least 5mn. Put some thread lock at the end or replace the screw to be sure.

Alternative ... from Quaife LSD. Next upgrade for tracks.

Bilstein Damptronic ...

GT3 is the best, cheap light and adjustable ... and OEM link will fit on the rear, not the front one, you have to cut 40mm to fit. I use my homemade one for quite a while (even on track ... perfect) and finish to buy some from Tarett. Cheers.
