GT3 RS wider front track on GT3 or Carrera?
As title says, is it possible to fit the front end of GT3 RS to the non-wide front track cars like GT3 or Carreras? I guess anything is possible, but curious to know how difficult it might be.
Thanks
Thanks

gt3 and gt3/rs are the same in the FRONT
the welded rear quarter panels are where the difference is and in the REAR + the rear wheel offsets - but underneath the mechanical stuff / suspension pickup points etc are the same
if by wide body you are talking RSR then that is NOT the same obviously
wrt a Carrera, I believe the gt3 and gt3/rs share the front section of the 4wdr Carreras as this section is stiffer than the 2wdr Carreras if that helps you

- the OP didn't state the model years
- the 5 lug 997 mk1s have the same offsets
- unless you cut the fenders on the mk2 RSs, the stick on wide body front fender attachments do not themselves allow a wider track - it is strictly cosmetic - it you have the GT2RS carbon fenders then I believe technically the front track can be wider but I believe the wheel offsets are the same
- all the track DE mk2 crowd (GT3 and RS) that run after market wheels I believe run the same offset on the fronts (i.e. the standard BBS 9" center lock front rim)

- .2 GT3 and GT3 RS front track are exactly the same?
- the stick on the front fender is cosmetic and doesn't mean that the front track has been widened, either through a different setup or wheel/tires?
I can swear that I read somewhere that front track of 997.2 GT3 RS is 0.5" wider.

Based on these websites:
- GT3 RS Front/rear track: 59.4/61.2 in
- GT3 Front/rear track: 58.6/59.5 in
So, front is 0.8 of an inch wider, while rear is 1.7" wider.

The .2 RS has wider track due to wheel offsets.
The RS has 9" wheels with 47mm offset while the base car has 8.5" wheels with 53mm offset. This nets 12.35mm on each side, for a total of 24.7mm wider front track, assuming identical alignment settings.
Bear in mind that both track and wheelbase can be changed with alignment settings.

^^^This is correct
On my mk1 narrow body gt3, I run an 8.5" ET51 rim with a 10mm spacer thus making it ET41. An ET41 8.5" would have the exact same track as a 9" ET47. So, as pointed out, the issue is the offset of the wheels - not the body work.
As I understand it, for TUV reasons (tires not extending past body work), the stick on attachments allow the tire (at the bottom) to technically pass this requirement.

To back this up, I run a 9" wide wheel with a 45mm offset on my narrow body (non-RS) GT3. This fitment is 2mm more aggressive than the factory .2RS wheels, and has effectively widened my "track" by 1.13" overall compared to my stock wheels.
To beat the dead horse, the length of all the suspension parts are the same between the narrow and wide body cars, and the distance to the fenders is made up with wheels of different offsets. If I wasn't running -2.8 degrees of camber, the top of the wheel would most likely be sitting outside the fender lip...hence the stick-on flares that the RS comes with.

Thanks guys, that's great information. Makes sense now. I never thought just wheel offset can change the front track as much as 1"!
The reason I was asking is the 991 wider track and how much it has improved front traction and I assume the same concept was applied to RS and hence it's a relatively cheap enhancement to help with front traction.
Now next question is, if one decides to go for the GT3 RS wheel size/tires, should one definitely get the fender lips?

No need unless your wallet is feeling heavy
You will also need the different turn signal lights in order for a flush finish
If you are a track junky order the after market front canards that many of the DE ****** have installed instead + the cup front splitter and crank your rear wing to max

The real purpose for the front fender lip extensions on the RS is actually for stone protection. Although wider wheels fit fine, there is more possibility of stone damage to the paint. If you just want a set of wider front track wheels, the front flares are completely unnecessary.
