Just pick the car up today from the local tuner (Gemballa Hong Kong) with the aerokit and 3M Stone Guard installed. Also the correct badge....Link to Photographs

Which emblem should I put on my Aerokit II (02' C2 Coupe), which will be installed next week? "GT3", "911", "Carrera" or just leave it blank? What do people in this forum do?

I have my local shop installed the 04 GT3 Wheels yesterday and the shop agreed that I can test the wheels out for one week and if there is any problem, I can return the wheels. Meantime, I still keep my Carerra 5-spoke. Since I do not want to spend any money on new tires (235/295) yet, I reuse the tires on the Carrera 5-spoke which is PZero Corsa 225/285. I went for a casual drive after the installation and at this stage, there seems to be no problem with the wheels: the tires are not touching the fenders from lock to lock. I will go for a hard drive this weekend to see whether there is any bumpsteer. The shop does not have any access to a bumpsteer measuring device. What does a bumpsteer feel like?

Many thanks for the prompt reply.

Would fitting 04 'GT3 wheels with offset 40mm/63mm to 02 C2 Coupe lead to bumpsteer? Currently I am using 18" Carrera 5-spoke with offset of 50mm/65mm. I raises this issue with my local shop today and the mechanic says that there won't be any bumpsteer with the GT3 wheels. Is he right or is he just trying to sell me those wheels? Any comments is appreciated.

I am also thinking of installing the Aerokit, so the GT3 will make the perfect match. Anyway, I was concerned that the increase in the front tire size would make direction changes harder. Presumbably, the car will also accelerate less quickly due to more friction and unsprung weight. Would it?

My local shop has a set of 04 GT3 18' Wheels (brand new) for sale @ $1800. Would they improve the handling of my C2 Coupe, currently fitted with 18' Carrera 5 spoke with 225/285 P-Zero Corsa? More importantly, would they make the handling worse assuming that I would use 235/295 tires? Many thanks.

My speedometer (the analog guage) has "Miles" as its units but I am more comfortable with "km". Is it possible to just change the face of the speedometer to those with the "km" units, or do I have to change the whole speedometer unit? Is there anywhere I can get the original Porsche guage faces as my porsche dealer won't sell me just guage faces, i was told that I have to purchase the whole panel including the speedometer, techcometer et al, which costs over $1000. Many thanks.

Great picture, Loren. I'll check whether the conditions of the duct when I change the tires coz the rear pilot sports are bald. Does anyone have any experience on P-Zero "Corsa"? They seems to be quite popular in my area for p-cars.

Thanks, Loren. I'll try to very careful at driveways. Where are the front brake ducts located?

Loren, I have 02 Coupe with Tipronic. It is mostly for street use with maybe 5 to 6 track days per year. Anyway, I just had the alignment done yesterday. I gave the 2004 GT3 spec (slightly different from those above provided by another person) to the alignment shop, as follows:- Front axle height: 115 + 5mm (115 to 120mm) Rear axle height: 128 + 5mm (128 to 133mm) Front axle: Toe unpressed (total): +8' +/- 2' Toe difference at 20¢X lock: -1¢X30' +/- 30' Camber: -1¢X +/- 5' Max camber difference, left/right: 10' Caster: 8¢X +/- 30' Max caster difference, left/right: 40' Rear axle: Toe per wheel: +13' +/- 2' Max toe difference, left/right: 5' Camber: -1¢X50' +/- 5' Max camber difference, left/right: 10' The alignment shop has a "Hunter" computer alignment machine and surprisingly, the software already has all the details of GT3, X74, ROW & USA M030, ROW & USA std alignment specs. and with detailed built-in instructions of what and how to measure ride height, etc. I compared the computer GT3 data with mine and they are almost identical- within 0.05 degree (3'). So I ended up using theirs. The alignment and ride height settings took three hours (I was there all along) and they tried to set everything up to within 0.01 of a degree. When I went into the shop, they measured the ride height and the front has 132mm and rear 110mm (what a joke). I guess it takes longer for them to get the job done because this is their first P-car. Anyway, I am very pleased with the job and they charged me US$230 (This is a more expensive package where I can go back and change the spec anytime within one year free of charge). I cannot find a shop in my area that do corner balancing and I think I'll have to stick with the current settings until I find one. Do you the 2004 GT3 spec. is suitable and appropriate because i can always go back and ask them to change it. Many thanks.

I've just installed a set of Gemballa one way-adjustable (bump/rebound) coilovers suspension, which are basically H&R units with H&R springs. I was told by the local porsche specialist (the only one in my area) that no alignment is required for lowering the car by 30mm. This makes me worried because I would like to have it aligned properly and preferably corner balanced. Since the mechanic is not interested in doing the job, I have to take the car to do alignment elsewhere. Would any professional alignment specialist with the right equipment know how to align a p-car? The problem with these specialist in my area is that they have no experience with p-cars (mine will probably be the first p-car they will lay their hands on) as they are mostly involved with WRX, EVOs, Skylines, Merc, BMWs. They have a "HUNTER" machine. If they do not have the correct parameters to aligh the p-cars, can I use those in this forum-are they sufficient or further parameters are required? Additionally, can someone explain how to properly measure the ride height so that I can make sure that all four wheels are lowered by 30mm. Then, I can take it to an alignment shop to dial in the GT3 spec. Can someone please verify that this is the GT3 spec:- Rear Axle: Camber: -1.50 degrees +/-.10 degrees Toe: +08' +/- 05' Total Toe +16' +/- 10' axle angle: 0' +/- 10' Front Axle: Caster: +8 degrees +/- 3 degrees Camber: -1 degree +/- .10 degrees Toe: +03' +/- 03' Total Toe: +05' +/- 05' I would appreciate your valuable advice on the above. Many thanks.

Hi, I am new to the forum (as well as Porsche), and yestrday, I came across the following two 996s:- 1. ‘01 C4 with GT3 kit and wheels, 6000km, silver with black interior 2. ‘00 C4 20,000km, black with gray interior (costs US$7k less) The ‘01 C4 is extremely new and well looked after, the condition of the ’00 is also quite good. I test drive only the ‘01 C4 and find that I can live with one of these as a daily car (currently ‘01 E55 AMG), and immediately fell in love with it. Is there any difference between the ’00 and ’01 C4? Which one should I go for? I have not considered the C2 yet. Does the AWD in the C4 make a big difference? Would be grateful for any valuable advice.
