The Intrax 4ways comes with top mounts for the fronts shocks .ThomasC2 I dont run any spacers its all achieved with the inner and outer barrels of the 7Cup wheels, thats one of there distinct advantages.

What was involved here? Any weights? I've been researching this with Freno's carbon carbon set up and the gains look incredible when combined with rs hubs and bbs...please let us know the details!

The wider track comes from moving the front suspension longitudinals from the inner mounting holes to the outer mounting holes. This increases track 30mm per side for a total of 60mm.
You can further increase the track if desired by switching from 964 to 993 longitudinals, when this is done in conjunction w/ the mounting hole change you get 42mm per dide for a total of 84mm increase in track width.
The change for 964 to 993 longitudinals alone increases track 12.5mm per side, for a track increase on 25mm
993 ABS wheel uses 48 teeth, 964 has 45 teeth, usually you use the 964 ABS wheel w/ the 964 ABS brain but sometimes when brakes or tire od is changed it's necessary to change that

Ok, it's 25 mm then and I did say it is because of the 993 longitudinals and not from the uprights.
The ABS sensors on 964 are mounted in line with the brake disc, on the 993 they sit facing the disc from the side. Therefore the "meassurment teeth" at the end of the sensor will sit in the wrong direction over the ABS cogs if you use a 964 sensor. The 45 teeth 964 cog works just fine.

Tks a LOT for the cheers guys, great to read!!!!
Lots of great info coming in this thread Big tks to Bill and Thomas! Its very nice to have all this info in one thread.
We didnt change the Longitudinals, maybe this is worth doing I dont know?
Regarding PCCB weights on a 997 going from steels, 380mm fronts and 350mm rears, theres a 22kg difference. Im figuring I loose som 18-20kg due to smaller discs on the 964.
We used a 25.4mm Master Cylinder from the 997GT3RS but had to change the Brake booster from the 964 to a 993 booster. New Bells were manufactured. For the centerlocks the 964 hubs were used and modified. Its the good ones from the Cup cars not the ones from the 7RSs thats get loose.
Currently on vacation so I dont have a lot of pics to show at the moment but will try to remedy that later.

One interesting thing Ive read about the amazing Roock 993GT2Evo cars are that they had an additional 7cm wider track compared to the works cars, does anyone know how they achieved this?

That is a very desirable mod for lots of big brake setups and would help a lot of us to know for sure.

Regarding the fit of the GT3RS master cylinder and the 993 mc we didnt do anything but change to the brake booster from the 993. If you look at the pics of the two M/Cs they look very similar, from my reciollection if you have 964 M/C you need to change the fittings.
As to how the feel of the cylinder is I cant tell how the larger cylinder feels with different Calipers etc.

factory 993GT2evo used 10x18 ET32 wheels in front, a 10 ET28 would raise track by 4mm per side.
track for the factory GT2 Evo w/ the above wheels was listed as 1460mm in front

Most 964 owners that install a big brake kit also swap in the 993 vacuum booster and m/c(alternatively an electro-hyd setup as used on the RS and turbos can be swapped in, but that's a lot more work and expense)
The 993 m/c is 23.8mm, it would be very desirable to have a 25.4mm m/c in there.
