Try this out, change the rear toe to positive 4 and test, if that introduces to much wiggle in the rear than back off by one click till you hit a comfy point; adjusting the rear toe will aid in the understeer by helping to get the back end in the right direction.

Since this is an FF it won’t have the effect of “driving” the back end around a corner, there is no power to those wheels. What it will do is help to “rotate” the back end around the corner as the weight will be loading to that side, but it could produce too much tail wiggle. Note that I am using “driving” and “rotate” loosely.

I actually looked at that before posting the above reply. As a rule of thumb I don’t use LSD unless it is 450hp or more; however, I have run into a few cars in GT3 that benefited from having LSD and where below the 450 line. If adjusting the first gear a little more does not help than I think it is just something you will have to live with or sacrifice performance for a higher TCS setting.

I mean lets face it, we are talking about a stage two turbo slapped into a front wheel drive, when it spools up something has got to roast! I am assuming that the tires are burning up when it spools right?
