Let customers speak for us
Great quality. Great customer service
Quality craftsmanship!
My golf mk7 Gti is already modified with various chassis and suspension upgrades. After fitting these camber plates, the car has improved dramatically. Much more dynamic and improved turn in. Also big improvement in traction out of corners/ around bends I can get more power down and earlier.
Superb quality, machine work and hardware. Well packaged and quick delivery.

Installation was straightforward. My car is a AMGGTC Track you only I was getting outside where on driver side front I leave for the track this Thursday for three days of DE driving I’ll let you know how it goes.
I came across Suspension Secrets by chance on youtube, and decided to check them out. their offering is very structured and website contains a lot of cool information about racing and suspension in particular. Matt is extremely knowledgeable on the subject, and quality of the product is superb. I ended up buying the Track Package for 992 GT3, which transformed the car. They also gave me full specs on how to set everything up. Cold not be happier, I'm your customer for life now!
Worth the purchase price and time from the UK, well built hardware that looks like jewelry for the car.
