Why take the chance you say?
I used something called logic.
Our cars are economy cars said:
I can go around a track on a pogo stick. Doesnt mean it's gonna be the fastest or most reliable way to do it though. These things dont even advertise what spring rates they're using.
Ive also done plenty of reading on these things from back when i had a GTi. Yes, there are lots of people who said they were fine, but if you read closely, a lot of those owners had only had them installed maybe a week to a month. Read deeper and long term, seen many complains about endlink brackets ripping off, strut mounts cracking. Ive also read that these coilovers are all pretty much universal. Same strut/spring design, just different mounting and length. Which means there's no R/D beyond will it fit. Meaning, yes, you'll go low, yes you'll have adjustable front camber, but it's gonna handle like crap regardless of the quality.
