How would any make your car handle worse?
Surely it's just adding adjustability to the rear end, so handling will be as good as the set up?
Correct me if I'm wrong, and there's genuine design differences, but I would expect that build quality would be the only issue?
I've been looking into what beam to buy for a while now and read a fair bit! Seems it's not in common for a few cheaper home made beams to not be genuine 6 degree beams and they can make the car feel worse than standard on the limit. I guess you get what you pay for. Any one can buy a welder and make one don't mean there doing it right lol
