Voltex Initial Sketches for the Honda S2000

Evasive Motorsports has been working with Voltex of Japan to develop new aero for the Honda s2000. They are well known in the EVO and WRX/STi communities for their work on the Cyber EVO and Cusco Impreza WRX. We have convinced them that there’s a high demand for quality aero in the s2000 community. So now, we bring you the initial sketches of the design based on our feedback.

The aero kit will be a AP2 bumper add on, complete with sidesteps and rear diffuser. Optional canards and splitter will also be available for those looking for additional down force. The splitter will also be available in honeycomb dry carbon for extra strength. Voltex conducts wind tunnel tests all their parts to obtain data to make changes if necessary. Stay tuned for updates on development!

Evasive EVO X tests new Tein SRC

Thanks to Tein USA we have the opportunity to test out the new Super Racing Damper for the EVO X. From initial impressions the shocks look similar to the EVO 9 setup except for the rear external reservoir now mounted remotely. The EVO X SRC offers motorsports valving and M.S.V technology which should perform better than previous SRC dampers. We will be installing this on our shop car and hopefully to have these tested at the track soon. Check back with us for updates more information.

Evasive now offers full race preparation including alignment / corner balance / suspension tuning!

Through years of experience at the track, we’ve recently decided to offer suspension tuning to our customers in the Los Angeles area. We offer wheel alignment, digital corner balancing, and general suspension installation and tuning.

We offer different setups depending on your driving style, car modifications, and intended purpose of vehicle. We are available after hours and weekends for those of you that need last second jobs before track events. Please call us during our office hours to schedule an appointment.

HKS Hipermax III S2000 Sport Coilover Review by Rob Walker of Maxrev.net

Just got back from the track day and I had some interesting results.

Before we get started.. I have owned the following sets of coilovers for the S2000.

– KW V3
– Tein SRC
– Custom Valved Motosports Bielstein (For R-Comp)

and have tracked the following systems:

– Moton CS
– JRZ 2 way
– H&R

Installation: Install was fairly straight forward.

Few things that I liked about the HKS…

HKS comes with all the necessary wire ties, bolts, brake line bolts:

Brake line hardware:

Group shot of the Bielstein, KW & HKS:

I liked that the HKS was perfectly set to the recommended settings out of the box. The preload/ride hight was exactly as HKS recommends on the manual. I also liked that both of the rear shocks has the damper adjustment knob built in. Each click was easily recognizable and easy to access.

Testing was done at Buttonwillow raceway on a 95F summer day.

I ran 3 sessions in the HKS and 2 session in afternoon with the KW CS. The car is a 04 AP2 with the following mods:

Volk Wheels, 255/40/17 R1R Toyo Street Tires, Voltex Wing, 60mm Single Exhaust, Spoon Calipers

The HKS was installed first and aligned the day before the test day to my street tire specifications. Ride hight was measured before and after the installation of the KW to minimize alignment changes between the two setups. I also tried to equalize the gas weight by filling up between each suspension setups. Both suspension started the test at the recommended damper settings.

HKS was much sharper to respond to steering inputs and seemed to use the tire more effectively on the track. The single adjustment on the valve made it very easy to optimize the damper setup.

The KW was more forgiving and more compliant over the surface irregularities but felt less responsive when compared to the HKS. The KW would set into max roll fairly quickly and took much longer to transition from one side to an another. (lateral transitions)

KW CS.. is pefect for stock-ish S2000 with occasional track. It’s definitely more livable on a day to day basis. It’s a great system for aggressive street/ occasional track coilover. KW will be also very forgivable to various type of tires that the owner may use. The HKS, on the other hand, will require fairly good tires to use its full potential.

For my setup, the the HKS Hypermax III Sport (woa.. long product name..) was faster on the track by about 2 seconds. I adjusted the dampers settings on the HKS and ran my personal best of 2:00.05 with the HKS. However, this does NOT mean that the HKS is superior in any way.

Even with my best efforts to keep the alignment changes in check, a real test should involve an alignment check after the suspension swap. The ride hight recommended by the HKS shocks was also used in the testing and may have not been optimal for the KW.

I also think that my agressive street setup (non-staggered, R1R, wing) was more well matched when combined with the HKS. The results could have been different if a stock AP2 was used in the test.

On the road, the KW is definitely more compliant and smoother. Road comfort is more of a preference but the HKS is harsher on high speed valve inputs from the road.

You won’t go wrong with either system. I would recommend buyers think about how they are going to use their car and what type of mods they have in terms of the overall balance of the car.

If you’re planning to modify your S2000 for lap times on Street tires, my choice would be the HKS. My impression on the HKS system was positive, and it showed in terms of lap times as well.

Project Mu G-Four Brake Fluid

Project Mu G-Four Brake Fluid

Super high temperature rating 335 degree Celcius (dry boiling point). PMU G-Four racing brake fluid is recommended for competition use and excellent for street use. Totally reliable brake fluid that combines a boiling so high it’s in another dimension with durability and maintainability.

Dry Boiling Point – 335 C
Wet Boiling Point – 221 C

We will be testing this fluid out to see how it performs with our shop Evo. From the numbers it looks pretty good!

The technology behind Swift Springs

Swift Springs was found in 1997 in Tokyo, Japan as a motorsports subdivision of Tokyo Hatsujo Manufacturing Co, Ltd. which has been leading in spring technology since 1924. They’ve just started making a name for themselves in the states and there have been no complaints from our customers yet. That’s why we recommend Swift made springs whether for a simple lowering spring upgrade or a custom coil-over spring application.

The following videos demonstrate the difference between typical lowering springs vs. Swift springs.

Typical lowering spring setup (non-Swift):

Notice how the coils bind every now and then during travel. This can create additional wear and damage to your suspension. Not to mention, it can mess up your track times.

Swift Springs on oval dirt track:

Swift Springs on oval paved track:

Watch the amount of stroke. No binding either. The big shock clearance also minimizes the chance of any contact between the springs and shock even under the harshest race conditions.

H5S.TW – Motorsports most advanced spring material
Swift Springs R&D created H5S.TW, which is a material stronger than regular silicone and chrome. This allows them to make the spring wire thinner. In turn, their springs need fewer coils which dramatically increases available stroke while decreasing weight significantly.

Weight Comparison Graph

Super linear rate characteristics
Unlike other spring manufacturers who test and optimize stroke at different rates on their springs, Swift tests the spring rate through the entire stroke to provide the optimal rate.

Swift springs are within 3% of the spring rate from 20-30% of the stroke all the way to about 80% of the stroke. (the average stroke range for most road race motorsports)

The entire line of Swift Springs and products is available through Evasive Motorsports. We also proudly use Swift Springs on our own project vehicles.
