KW camber plates have bearings to reduce flex and are easily adjustable for camber.
|
 |
The KW Competition dampers are independently adjustable for compression as well as rebound damping and have stainless bodies for smooth non-stick operation of the spring perches.
|
 |
| The rear KWs are still adjustable for ride height and corner weight even though they have an independent spring. Having a separate spring takes bind off of the rear shock and makes for a smoother ride and less tire shock. |
Suspension is critical for any track car and Berk uses KW Competition 2-way adjustable coilovers. The Competition 2 ways have independent adjustments of the compression and rebound damping and are calibrated a little more aggressively than KW’s Clubsport or Variant III lines. Velocity Motorsports supplied the adjustable links to adjust rear camber and caster as well as spherical bearing equipped swaybar endlinks. OEM E92 M3 sway bars are used for increased stiffness along with M3 front lower control arms for more negative camber. Polyurethane bushings are used to reduce subframe to chassis compliance. 18X9.5″ APEX ARC-8 wheels are used with Hankook’s Street Class dominating RS-3 tires to grip the road tenaciously. The track width is adjusted with Macht Schnell spacers and long wheel studs. An OS Gikken super lock 1.5 way differential distributes power to the rear wheels through a shorter 3.46 gear ratio.

Velocity Motorsports make these adjustable links to adjust toe and camber. They have spherical bearings to eliminate squishy rubber.
|
 |
Machined aluminum subframe bushings eliminate flex and increase the sensitivity to chassis adjustment.
|
 |
M3 lower arms for the front suspension are longer and allow more negative camber to be adjusted into the suspension.

The choice of Rotora brakes over the excellent stock Brembo’s is a head scratcher. Berk is in the process of switching to some uber trick Performance Friction brakes soon. |
The brake system on any race car is important. The Berk car relies on Rotora six piston calipers and 355mm rotors for stopping. We cannot figure out why the team would remove the stock car’s excellent Brembo six piston OEM calipers for what seems a downgrade but we will be helping them with a set of Performance Friction super brakes which you will see featured here in a few weeks! It should be no problem to match PFC’s claim of .2 seconds a lap or your money back guarantee! The brakes are fitted with Carbotech brake pads using XP10 compound on the front and XP8 compound in the rear. Ti Speed brake pad shims are used to reduce heat transfer into the ATE Blue brake fluid. Agency Power braided steel brake lines are used.

The rear two piston stock BMW brakes are pretty good as is.
|
 |
The front brakes have some serious ductwork going to them, needed for slowing the heavy car from high speeds.
|
 |
| Agency Power braided steel brake lines improve pedal feel. |
