No as I'm a pussy and babied clutch when I noticed it started to slip Old clutch did cause smell, though and I noticed it became slippery after few laps, poor thing never recovered from abuse, so needed to replace that clutch).
Also I can provoke it to slip quite easily, if I would do flat shifting it would be same as in test patch x30 with XRG(well, car weights around same and has around same amount of hp, bit less torque), that much of slip. But still if I add turbo and such it is differential, driveshafts, gearbox that will fail firs, then rods give up and after that comes clutch, even bastard can't take power shifting, it is ok when not touched
I have also tested few company cars in one of my previous jobs, as boss was disgrace to humanity, we then did put some abuse to his vehicles Burned clutch there too and while it takes some effort, it was clearly noticeable that if you just keep throttle floored and shift gears and do launches it does give up around similar distance/usage that 5 laps around BLGP would be, if one does not ease up at that point it gets ruined, but if one babies it a bit it is perfectly good to go after that(well not perfectly, but works). This with Japanese 70hp, very light station wagon.
Linkage problem causes only that 2nd gear is bit hard to get in, that shows in one tight right where you turn towards start/finish line again, corner before that tiny chicane.
And that 50/60euros is for whole day, which means 8 hours of driving, however I have been pretty satisfied for much less as it has been my only car, no rollcage and tires are waaaay too soft, I hope to get back there next summer with some improvements, though.
Difference between US market and European/Japanese markets are that here torque comes at quite high revs compared to US market, specially when talking about LFS era vehicles.
This of course has lead clutch to be much sturdier in US cars, I would imagine it bites quite nice, where cars in here have soft clutch that does not really bite but stops slipping. So when flat shifting such clutch is always in disadvantage as it slips lot and heats a lot in process.
Volvo clutch in other hand is quite harsh, it has 0% 40% and 100% settings that one can easily use, it bites really quick under normal driving, but still slips if I try to powershift.
However I have not much experience from US market cars, only what I have read and heard, so that is bit of question marks to be honest
Dynamic and static frictions are what I believe is where most improvement to LFS clutches will come as I'm not sure if there are both things now in, LFS does everything from some genious formula behind it so I think that is thing that Scawen was going to improve in future, but that man is sometimes bit mysterious when he posts
Sorry for typos, rushing to shop
