IMO, the car could be much faster if you changed the driver's driving style. He saws the wheel like a blade at a lumber mill. Smooth is fast. Tell him to stop twitching and fiddling with the steering wheel. Smooth inputs to the wheel and steer with the throttle.

Smooth is fast.
I'm sure that whatshisname could learn a lot from you.

Personally I thought that was pretty humbling to watch. The car was squirrely but he consistently unsquirreled it very well. Only one substantial mistake (looked like he overcooked a corner at 6:40 or so), but if the fastest lap wins, then it's probably a winning strategy to drive so close to the edge that you sometimes make mistakes like that. Just need one clean lap.

Thanks for posting that, garageGT!

I think you should take Pat's advice.
It's a reliable source

The active diff is doable for the 5mt (xfer gears and c-section) and you can get proper controllers for it as well, its been used worldwide for many years. with the proper setup it will be faster

I had the cusco tarmac gear center diff and cusco MZ diff in the rear. Loosen up the lockup ratio on the rear diff to around 60%. It helps quite a bit, at least it did for me. The high lockup ratio just resulted in an instant loss of grip and since the diff is OPEN, the rears get all the power once they break loose.
the tarmac gear is 35/65 with traction, 0/100 without. Loosening up the rear diff keeps the back end from kicking out so fast and allows the fronts to get a bit more power.

with low traction out back, the Tarmac Gear center diff is a drift diff. That's what I used it for initially.

Thanks for the input..we had the rear at %60 as well, but it was a RS unit. Cusco told us to switch to RZ as you mentioned. But they dont think their center diff is suitable for buttonwillow..They also ran there and had chance to fine tune their 6spd dccd setup, they want me to run that but its too costly for us to switch to 6spd after all the investment we did in the 5spd. Our west coast tracks are very slippery & rough. So we will try to increase grip by an EMCD & RZ setup, or simply a usdm 50-50 & RZ. I also heard early WRX came with a 60-40 split but have to do some more research..I always liked the 35-65 but its getting harder to control with more power. The car didnt have any traction problems when it was slower lol


cheers,

cenk

you can easily run the 5spd emcd with an active controller, we've had many out there winning hillclimbs, rallies and time attacks in europe, africa and asia...

depending on your current 5mt case (there are 4 designs), to convert your 5mt you just need the transfer gears, or if its a different case style then you'd just need the rear end of the 5mt case (or you can modify yours), then use the ver6 emcd. For high stress situations (yours isn't to be honest) the coils are also often re-wound. It depends if you currently have the 30/33 gears or 31/31 and which rear end of the case.

the 5mt and the 6mt also have some coil differences but you can order an active diff controller specifying the 5mt and there are proper maps out there for time attack and different circuits
