Differences Between the Porsche 911 GT3 and the Porsche 911 GT3 RS

A few months back I posted an article titled “I’m not a Porsche Expert but I Play one on the Internet.” The basic gist of this post (click on the title of the article if you want to refresh your memory) was for people to submit Porsche related questions to me. I would in-turn act as a free researcher for you.

Porsche-GT3-RS

Well, the questions keep coming in and I’m doing my best to answer them (if you have something you want me to research just use the link from the article above or comment on any post.) Those that are more interesting or fit a broader audience I end up using as a post for the site, like this one today. GTRacer wrote in and asked, “Please describe the difference between a Porsche GT3 and a GT3 RS?” I think I can sum up the difference between these two cars pretty easily:

The Porsche GT3 is designed for occasional use on the race track while the Porsche GT 3 RS is designed for occasional use on the road.

If that doesn’t do it for you, I’ve created a list of the differences below. Even better, I found this great video that really showcase the GT3 RS and how it differs from the Porsche GT3. I've put the video at the end of the post for you.

Here is a list of what is bigger, better and badder on the RS vs. the plain GT3 (if a GT3 can ever be considered plain.) For those of you that know more about this subject than me (and I’m sure there are a lot of you) please let me know what, if anything, I may have missed.

The Porsche GT3 RS as Compared to the Porsche GT3 is:

  • 44mm wider across the rear axle
  • The rear wing is carbon fiber. It is lighter with a larger surface area for more down force
  • Rear screen/glass is made of lightweight plastic saving nearly 3 kilos or 6.6 lbs
  • Contrasting color on wheels, side logos and exterior mirrors
  • The front spoiler is modified to create more front end down force
  • The interior is all black
  • Steering wheel is marked at 12 o’clock position
  • Standard feature include club sport package and lightweight bucket seats (optional on GT3)
  • 415 hp, 305 kw 405 torque. Top speed 193 miles per hour
  • 20 kilos (44 lbs) lighter than GT3
  • 301 hp per ton. That 4.3 more than the GT3
  • 1/10th quicker to 100 kph doing it in 4.2 seconds
  • Single mass flywheel vs. Dual mass in GT3
  • GT3 designed for occasional racing use
  • GT3 RS designed for occasional road use
  • Suspension is configured for race/competion driving
  • Rear track is wider than that of the GT3
  • GT3 RS has split rear wishbones
  • Wheel base is 5 mm longer than on the GT3
  • Rear wheel offset is smaller due to wider rear axle

    Nitro,

    I don’t remember where that came from, but I know it sums up things perfectly. Glad you’re digging through and finding the older posts. There is a lot of good stuff in here from back when I first writing and not many people were reading. :-)

    Saw my first GT3 RS (black and orange) at a Porsche track event, it sounded great, went like $%^# but I almost cried when I saw it up close, swirl marks, front splitter “splitted” and dirty…exactly what a Porsche was built for.

    I was so impressed with the “Cup sound” and those gorgious hips that when a “little old lady in a rush to get her grandson a birthday card cut across and took out my front end, that when it was in the shop I ordered factory wide body rear quarter panels (the body shop and local Porsche dealer couldn’t believe it…only the front end had been taken out) welded into my Carreas S, installed Fabspeed muffler bypass exhaust….chipped her and “outlaw’ with a nod to the bad boy RS.
