Perfect triangular control arm design allows very rigid, lightweight construction that in addition of all other benefits stated above, is highly desired for circuit racing applications. All control dimensions are adjustable, this also allows use of many different combinations such as spindle/knuckle swap on other chassis for example E30 5-lug swap.

How about the lifetime and service of the kit?

The kits have been proven on street and track applications by hundreds of our customers. We're constantly doing R&D to make the kits even better, all improvements are based on customer feedback which is very important to us. We have proven the very same bearings with no maintenance for 20,000 kilometers, through the year, in daily use without signs of excessive wear. When the bearing life comes to an end, they're easily replaceable! Bearings are available around the world from automotive and industrial dealers and any of the spare parts can be also bought separately from us.

We want to keep our customers 100% happy thus we're only using the best materials and manufacturing processes available. CNC machined parts; arms and rods are made of aerospace grade AW-7075 aluminum, highest quality CrMo tool steel and Grade 5 titanium is used on control arm mounting studs and fasteners, rear brackets are TIG welded structural steel.
