Can't change the ratio.. it's the rules and they do check ... but thanks for the advice..

About to put Super Pro 20mm front and 18mm rear.. seems to be the tuners choice on size..

I was of the understanding the cheaper model didn't have an LSD, only the GTS.

Only the Auto GT is an open diff.

Manual/Auto GTS is a Torsen LSD as well as the GT Manual.

GT Manuals have LSD's too.

To quote someone on the racing forum on here:

If you find the rear of the car too loose, the last thing you want is more rear bar. And with the limited droop travel you don't really want more rear bar trying to pick up on, and unload the Torsen. Just today pulling in my shop I got stopped dead when the right rear came up and there I was with no drive..... Who wants to make that worse?

What spring rates are you running on your car now? I would try swapping the front sway bar in first with the stock rear bar, then test with both new bars, then no rear bar.

This is for racing not drift?

Give it a try on the track before you spend the $$$.
I find the LSD great up until you get a rear wheel off the ground. Which I'm sure happens more often in a rally car than a track car.
I'm keeping the centre for now and will be looking for 4.9 or 5.1 gears.

Also, clutch pack LSDs can induce understeer where the torsen doesn't.

Hi Josh, I agree.
Having racing many cars with locked diffs the big disadvantage is that you can't get on the throttle too early as you tend to pick up the front and with a driving inner you understeer badly.. with these cars the advantage is driving through mid corner as they don't have the power to jump on the gas on exit..

I will run the car in.. see what times I can put in.. I have a good idea where I think it should be once I get my head around the lack of power.. no more 400rwhp !!!

It has to be kept in mind that I am running Dunlop D03 R spec tyres so grip will be good.. I think it's a matter of staying off the ripple strips.. in any case when you look at how light the arms are that's a given with these.. too many hits and they will break.. I do like the idea of the two way diff though.. budget is running out at present...
