It's just the usual map written/plagiarised by guys in Eastern Europe. Racingline just resell it with their usual massive mark up. They will never get another penny from me. They are a useless bunch of clowns.
I was offered one of their maps for testing and review in return for driving up there and helping them out with their intake kit (which never amounted to anything), but they said "Oh, we don't have a file for your car on the server"
I'd have been pissed if I'd driven all that way to pay for it!!
Don't give them your money either. Go with R-Tech or Revo etc. RacingLine embellish everything they sell, don't believe their marketing BS and pretty website. It's all hollow nonsense.
I did quite like their Spring/damper kit initially, but it proved way too soft for my kind of driving and I got a massive understeer moment with it aswell, which the knackered standard suspension never did, and neither do my coilovers. Same corner, same tyres, same entry speed. The Racinglines nearly spat me off the road. They didn't actually make it. They put black paint over the original orange, who ever made them. Cheap Konis possibly. They just specified poor damper rates.
So no, I really don't rate their products at all as you can tell by my scorched earth fury
