If the car is lowered it's probably bump steer. Standard suspension, stage 1 eddy, hands off the wheel, nail it on a flat piece of road......zero torque steer. I do get some tugging on the steering wheel under power on bumpy B roads, but that's bump steer induced.
Could have been, but I might have expected it not to be affected by the addition of an LSD. Otherwise, suspension is Bilstein B12 Pro Kit, WALK, at the time S3 arms and Eibach ARB's with stock geometry. On a flat motorway slip road it could be routinely demonstrated.
What seems to be clear is that there can be conditions present that can mean it affects some cars more than others. I deliberated for ages over buying these parts as I wanted to make the car track day capable and didn't mind the compromises in biasing the car in this way. I do agree with a point you made somewhere else in that manufacturers get stock cars set up pretty well but they are often focused neither one way or the other and please most people most of the time.
It's weird isn't it. Not sure how or why an LSD would have any influence on torque steer. ATB type differentials usually make it worse! Case in point: MK1 Focus RS! What else did you fit at the same time?
I was reading in that MK6 thread about some OEM parts to make the wishbones equal length, which will kill TS mechanically, once and for all!
I've driven a lot of hot hatches and the MK5 and MK7 are setup 85-90% capabale from the factory imo. The remaining 15% is people tuning the feel for track work and lowering etc. A standard MK5/7 can be thrown around at mega license losing speeds on any road and I often wonder what kind of ludicrous speeds people drive at on public roads to need coilovers and massive brakes, to top an already massively talented chassis!
I've heard of equal length drive shafts having an effect on TS but not wishbones, but I know very little about chassis dynamics etc so am in no way an expert. I simply took JKM's advice on setting up and bought as per their recommendation which has been successful. As I grew more proficient on track I outgrew the S3 front brakes and changed to the AP kit I have now. I'll be the first to admit that they are bigger than I need without a doubt and BG Developments did say as much. A neat little 4 piston kit would have done fine. I went for the 6 piston kit for economic reasons as it was barely more expensive and I thought it would appeal to wider audience when sold if removed for sale. What I have also found is that the pad area is so big I don't need exotic compounds to stop the car as I like and I also wanted floating rotors. But yes, I agree, not really required to get the job done, especially for road use. For road use only the S3 parts were fine, they had the required bite from cold and could take a few hard laps at Goodwood but would eventually give out and default to the ABS zone with no progression or feel. If you got into that situation on the road I'd say you were driving like a tit.
There's only one coilover I'd want and it's Ohlins Road and Track and at £2k thereabouts it isn't going to happen. Its dual valve feature is a great feature for a car used on the road. I had something similar in Koni FSD's on a 2008 Leon FR which had truly awful damping in stock form. Otherwise CO's are too harsh, for me at least.
Good quality dampers and springs which are properly matched and fitted with complimentary ARB's is still better than I am on track. The limits are far far beyond anything I have ever experienced on the road. So I agree completely with you on that point. Good geometry with -2 degrees if you can get it set and a WALK kit to deal with toe angle changes would probably do.
Tyres are one of the best mods for a car going on track, they'll give you measurable benefits but you need a well sized gentlemens' area to see the benefit and some ability

The Wavetrac diff is supposed to be different to conventional torque biasing diffs, I couldn't explain the differences but see if this makes sense to you

It's very easy to ruin a car with the best of intentions.
On the Mk7, I have a standard GTI in manual form and it's wonderfully capable. Truly brilliant. It may 'only' have 210 bhp but you can access a lot of that without any bother, and you are really moving when you do
