[FIA GT] FIA GT Technical Question - Differentials?

[Shane001]

Hi Guys,

Just new to this forum but hoping someone might have some answers, or links to a website with further information.

I've just spent about an hour searching google and can't find a direct answer.

What type of diff do the FIA GT cars run? I'm assuming they are running lock diffs?

The reason I ask is I'd like to confirm my understanding of how the cars in the game GTR handle due to the diff characteristics, especially in low speed corners. There's been a lot of debate about how these cars should handle in lower speed corners, specifically the difficulty of navigating a slow speed corner (ie 1st/2nd gear) quickly without spinning out.

Thanks

Most of the cars in the GTR game will have a tendency to understeer--as they do in real life. Push from the diff may only be part of the reason (which could be nearly 'dialled-out' as the diff ramps are adjustable in all the cars.) Being front-engined (ex the S7 Saleen) does not help. (Can't comment about the NGT//GT2 cars)

In most cases, just let the car do the work and don't try and push. Traction is generally excellent on these cars so the car is unlikely to move from understeer to snap oversteer in a millisecond. (unless the tyres are cold!) Wait until the front-end bites and ...............................boot it. Remember, these cars have a lot of torque so be sure to have lined the car up in a straight line before you give it some.

Technical regs used to be on the FIA GT website for download as a pdf document. Have you tried there?

audi r8r - yep, spent half an hour on the FIA GT site, couldn't find any info.

canam - thanks for your suggestions, but I'm really wanting to find out what type of diffs these cars run.

OK, TonyTone in the GTR forums just posted this link for me;

So the answer is Limited Slip Diffs!

Thanks everyone for your replies
