Hi guys,
So, these springs are really good. They aren't "amazing," "incredible," etc., they're better than good, but not great. What do I mean? They don't lower the car 'substantially,' it's only a very conservative amount. I wasn't looking for "scrape the pavement," but I did think the car would have a bit better stance afterward. These springs are tight, it feels like they do improve cornering, the car drives great, no complaints! But I'd probably look for something more in the range of -30mm to -40mm next time (or just roll into coilovers).
Happy Holidays!
Mark
