ASM S2000 CR Demo Car: Suspension, Chassis Braces, and Other Bits

June 4, 2013 by Aaron in ASM, ASM S2000 CR Demo Car, Spoon

After getting started on the exterior of our ASM S2000 CR Demo Car we move on to the other parts of the car.

As always, we lay out the parts and plan out the installation procedure to make sure things are installed in an efficient order.

First we lower the front subframe. This allows for installation of a number of parts such as the Spoon Subframe Rigid Collars.

The lowered subframe also makes it easier to remove the steering rack bolts which need to be replaced to accommodate the longer bolts of the ASM Front Bump Steer Kit. At the same time, this gives us an opportunity to install the ASM Front Tower Bar GT -Short and the ASM Front Lower Arm Bar GT -Short. Both of which also require removing the steering rack bolts. The “-Short” denotation refers to versions of these bars that are specifically designed to accommodate the 20mm spacer that is installed below the steering rack. This picture is a great representation of how the whole system works together. The ASM Front Tower Bar GT connects to the rear bolts of the steering rack to the front shock towers while the ASM Front Lower Arm Bar GT connects the front bolts of the steering rack to the sway bar mounting point on the body. These two bars combined adds 4 additional points of triangulation between the body and the subframe. In addition to the rigid collars, the subframe feels as one with the rest of the car and suspension feel and response is dramatically improved.

The ASM Front Bump Steer Kit reduces front bump steer on lowered cars by spacing the steering rack up and back to correct the angle of the tie rod to the knuckle. You can also see the mounting point of the ASM Front Lower Arm Bar GT to the front bolts of the steering rack.


The ASM Front Lower Arm Bar GT has 2 components to it. The first part reinforces the rear section of the front subframe to decrease flex in the open part of the subframe. The second part is the section that braces front steering rack mount on the subframe to the sway bar bracket attachment point on the body.

Moving on to the rear part of the steering rack, the ASM Front Tower Bar GT attaches to the shock towers and then down to the rear bolts of the steering rack. This further prevents subframe flex and ties crucial suspension points together for a very direct suspension feel.

Another item that can be addressed while installing the ASM Front Lower Arm Bar GT is the ASM Front Adjustable Stabilizer Bar since one of the mounting points is already removed. The ASM Front Adjustable Stabilizer Bar is designed to be close to factory spec but offers 3 steps of adjustment. Excessive body roll should be addressed with harder springs, not harder sway bars. ASM Stabilizer bars are designed for fine tuning the overall balance of the car with 3 steps of adjustment. You can also see the mounting position of the ASM Front Lower Arm Bar GT

We also have some Spoon bits to install up front. First up, a set of Spoon Full Spec Dampers with the standard 14kg/mm front springs. We’ve had great experience with these using them on all our Demo cars.

To increase the camber range of the front suspension we use Spoon Offset Ball Joints which are made of stainless steel instead of aluminum. These increase the amount of negative camber range by 2.5 degrees.

Can’t forget a set of Spoon Monobloc Calipers. These rotors have taking a beating on track but that’s the great thing about Spoon calipers, OEM sized rotors are used so replacements are cheap and readily available.

Here we can see many of the components how they all interact with each other in one shot.

Moving on to the rear end we finish up the rigid collar installation with the rear subframe.

Then the rear coilovers of the Spoon Full Spec Damper Kit with the standard 12kg/mm springs.

To reduce rear bumper steer and allow for independent camber and toe adjustment we installed a set of Spoon Rear Control Arms. These are made of stainless steel for maximum durability and strength unlike most aftermarket manufacturers who use aluminum.

The ASM Rear Stabilizer Bar completes the set to allow for fine tuning of balance.

The Spoon Rear Cross Beam Bar replaces the weak factory one.

Tying the front and rear subframes together for an additional point of reinforcement we installed the ASM Floor Ladder Bars. These attach rear most attachment point of the front subframe to the forward most attachment point of the rear subframe.


When the ASM Floor Ladder Bar is used in conjunction with the Front Lower Arm Bar GT, the Front Ladder Bar GT is required due to clearance issues.

Moving on to the engine bay we installed the iconic Spoon Yellow Valve Cover.

Topped with a Spoon Carbon Kevlar Plug Cover.

Can’t forget the Spoon Oil Cap and Spoon Radiator Cap.

The ASM Oil Filter Bracket prevents the oil filter from coming loose during racing conditions.

An ASM Steet Oil Catch Tank catches blow-by oil through the PCV systems. This keeps the intake manifold and valves clean from blow-by oil buildup over time. On the race track, the catch tank catches a significant amount of oil.

For increased durability and capacity, we installed an ASM Radiator Overflow Tank.

The most eye-catching part of the engine bay is the ASM Ram Air Cleaner. Jointly developed by GruppeM, the ASM Ram Air Cleaner provdes fresh air from the grill area and has a ram air effect to force air into the air filter creating more power at speed. The large section after the filter provides a large volume of air on tap in front of the throttle body for a strong initial throttle response. A beautiful carbon finish and smooth internals tops it all off.

The front radiator support is closed with the ASM Radiator Plate for the ASM Intake.

So we don’t have lay the factory hood prop on the intake system, we installed a set of GReddy Hood Lifters.

That’s it for this stage. More to come of course…
