Hey everyone, I know this has already been discussed, however I wanted to know if any of you had some links regarding the specific technical differences between the two cars. Also, even if not related to ferrari, in case you do have some info links on GT3 cars technical regulations it would be great (the FIA has some stuff on their website, but it does not go into a very technical detail). Thx!
Well, I must have missed that discussion. 458 GT3 and GT2 are ones of my favourite racing cars to talk about. I know the basics specs. as well, about GT3 and GT2, but especially the GT2 spec had transformed into few racing series, each conforming to its own detailed rules. So we have 458s in many specifications, GT3,GTS,GTE,SGT, LMS etc. But as a main starting point we can take the 458GT3 and 458GT2 specs. Engine and gearbox parameters should be close in each derived racing series so it should be easiest to define. More comes to the suspension changes and aero, maybe brakes even etc. From what I've already known, the GT2 is much more advanced car for the track, it's the proper racing car and GT3 is a mild modification of serial production car, prepared to race. Do you need the basic comparison between the two, like engine etc actual horsepower? Personally I am into discussing the cars details, rather than analysing the FIA rulebook. The rules for cars in racing series are endless and changing with such factor as Balance of Performance etc. Anybody passionate about the 458 GT2 & GT3 highly welcomed here.
The GT3 is far more than a mildly prepared road car. It is a real racing car with specifically designed aero, suspension etc. the engine block comes from the road going car, but things stop there. The GT2 actually known as GTE is a real prototype racing car with a real racing engine and 'box. The restrictors and aero restrictions (notably in the US GTD version) play a key part on both cars performances.
Buon giorno caro and Happy Thanksgiving! I trust you were at SRO awards to receive your well earned Championship trophy?? See you next year for more fun!! IlDottore(Stephen Earle MD)
Sorry, "milder" modification (than GT2) I should have said, to be more clear. Mainly I was focused on engine output. Everyone can see that 458GT3 is a fully fledged racing car, prepared to race under GT3 series regulations. It's hard to talk about such things like e.g. suspension changes/setups/gearbox to visualize them, and some external solutions, like aero, everyone can see by himself, but we all like numbers so as a starting point - engine output comparison (in general, not of a specific racing serie /rules can also change by year/) 458 Italia: 570cv/540Nm 458 GT3: 550cv/550Nm, no change in revs (9000/6000) 458 GT2: 465CV/520Nm - air restricted at 6250, max torque coming 500 rpms earlier(@5750).
Continuing.. So far, the best "link";-) I know, about Ferrari GT-xx cars is Peter,ChalStrad.(Nice to see you here .) But we cannot grind him about so much, because he is now busy keeping the secrets of the(also his) XX LaFerrari . OFF-T but I'll be mad if the AbuDhabi showcase reveals nothing to the public yet. Oh man, why wait so long .
Hi there, Good Doctor!!! Yes I was last night and it was awesome!! HUGE trophy and heavy as hell!! Are you coming to Abu Dhabi? Hope so!!! All the best dear friend!
No,not this year,too much surgery already scheduled and "Il Capo di tutti capi" doesn't want me in this part of the world with everything going on...en boca al lupo!! IlDottore
We are a group of "track day" enthusiasts and I just moved from the 430 GT3 Scuderia to the 458 GT3. In our group, we do have 458 Challenge Evo, 458 GT3 and also a 458 GT2, build for trackdays (with ABS and NO restrictors, so about 650 HP) I drove all of them and I also owned a 458 Italia and got a 458 Speciale a few months ago. So I have some experience with the entire 458 Family. Even if I'm not such an experienced and fast driver like Peter. As Peter already mentioned (and he has much more experience than I have) the difference in performance between the Challenge / GT3 and GT2/GTE is huge. The performance advantage comes mainly from the Suspension (including different whishbones), aerodynamics and electronic. GT3 and GT2/GTE also have real racing Gearbox (Hewland). Fur sure, there is also a difference in weight. GT3 is almost 100Kg lighter than a Challenge and if I'm not mistaken GT2 another 50-60KG lighter than the GT3. I would call a 458 Challenge is a race prepared serial car in terms of engine, gearbox, chassis. GT3 is another world. Due to the regulations (air restrictors) on some tracks GT3 and GT2 Laptimes are very close but if you throw out that bloody air restrictor the GT2 will be much faster than a GT3. and there is also a huge difference in maintenance. Running costs for a GT2/GTE are enormous while a GT3 is relatively cheap (compared to the GT2) And, I'm already in Abu Dhabi
Very appreciated, chrixxx. Great. I have been curious for long long time how these things would look like 'without restrictors' ;-). The GT2 is undoubtedly the fastest through the corners and best 'planted' of them all, ... and I only missed that top end speed thing of it. The 458 challenge (without 2014s Evo wing) seemed to reach the highest top speeds..? but even better fun is the speed carried out of the turns, so GTs win. 458GT2 with 650hp - amazing . Understandably for private track days only. But it must be astounding to experience that. So the GT2 for most performance, and the GT3 458 wins me of them all by its looks. Beautifully sculpted fenders, aero details, and overall stance with the rear wing. Awesome cars. Internal instruments panel seems to differ also between them, although I haven't seen exactly all the details. And paddle-shifters has been allowed in 458 GTs,same as in Ferrari challenge (although different gearboxes). The GT season ends, great competition year and next GT Championship Titles for Ferrari. Best regards from my humble person,
difficult to really compare in laptimes but Italian GT Championship Pole Position in Mugello this year was 1.48 and a Pro Driver tested my friends unrestricted GT2 last year. He did a 1.44... enough said!!
. I'm already looking forward to the 2015 GT's season. Btw, Have a nice week in Abu Dhabi. The XX LaFerrari is coming .
Great explanation, but it is actually even more complicated than that!!! Firstly,mother GTE in the ELMS Championship has bigger restrictors than for the WEC and Le Mans (+ about 50 bhp), then you have the whole issue of the Balance of Performance which varies depending on which championship you race in!!!! I'm on my way to Abu Dhabi!! Be at the track Wednesday morning!!! Brought 2 cars
You might also have a watch here... https://www.youtube.com/watch?v=GB4UjvamC4Q Essentially, comparing the GT3 and 2. CW
Do the race cars have a proper upper wisbone at the rear, or do they use the same configuration as all Ferrari street cars, that is, an upper single transverse link and the small moment reaction link from the upright to the lower arm?
GT2 hope this helps Overall length 177.87 in Overall width 80.15 in Height 45.67 in Front track 67.71 in Rear track 66.45 in Dry Weight 2745 LB Maximum power 346,75 Kw (465 CV) at 6250 rpm Maximum torque 520 Nm (50 KGM) at 5750 rpm Aluminium alloy engine block GT3 Overall length 181.06 in Overall width 80.07 in Height 45.55 in Front track 68.03 in Rear track 66.57 in Dry Weight 2678 LB Maximum power 550 CV at 9000 rpm Maximum torque 550 Nm at 6000 rpm
Thank you all for the interesting info! Also, in case anyone knows the answer to ingegnere question it would be nice to know
Correct, the video shows the difference in US Specs only. I wouldn't be surprised to learn that ELMS and other FIA specs are different. However, if a US spec car is going to race at Le Mans or the Euro-spec cars are going to race at Sebring, they would have to conform to the relevant series specs. CW
The cars run always by their specifications within the series they belong. Doesn't matter if the race is held in US or Europe or Eastern Countries. BTW. One thing which can vary from US and Europe tracks is loudness limit? But I dont know if it applies here. Just a digression.
Interesting, because this is in conflict with what I've been told. For example, when Risi took their GTs to Le Mans, the ALMS configuration had to change, and they had to conform to FIA specifications. CW
Hello, If I couldn't have clearly got your idea, then at least you could have tried to get mine. Le Mans 24hrs or "Sebring 12hrs" would have been enough said. But you now got my idea about single racing federation generic races around the world.
