Super Lap Battle Finals 2010

Posted on by

So SLB 2010 is over. TEIN engineer, R&D assistant and myself spent 2 days at Buttonwillow Raceway helping our sponsored vehicles. This year there was a smaller field but I think the level of competition and caliber of car was high.

Now on to the cars that we sponsor.

EVASIVE MOTORSPORTS

EVO 9 – Limited AWD
Driven by Mike C. co-owner of Evasive. Mike and the Evasive crew chased down minor gremlins throughout the event and never really got a chance to set a clean hot lap. Super Racing coilover with special 3-way rears. Best Time 1:51

Civic Si – Street FF
Also driven by Mike C. Testing out his newly modded engine and some aggressive suspension settings on his customized Mono FLEX dampers. Look for this next year after Evasive gets more testing done. We think it is capable of sub 2 min. lap times in the Street class. This year Best Lap 2:02

S2000 – Street FR (Evasive Sponsored)
Owned and driven by Tim Kuo. Very quick lap times considering the amount of modifications (almost stock NA motor) and no crazy body mods. Super Racing suspension and specifically chosen menu of mods. Best Time 2:02

CR-Z – Hybrid Class (Honda Tuning Magazine)
Also driven by Tim K. Very light mods since the car is so new to the US. Running our US spec. Mono FLEX coilovers and Falken 615K. Best Time 2:18.

Crawford Performance


2011 Scion tC – Limited FF
Driven by new up and comer, Michelle A. Quirt put this car together in just 2 weeks. Right now the car sports only a few light modifications. Running our proto-type Super Street coilovers. Best Time 2:14.

DC Sports


S2000 – Street FR
Owned by Mr. Will Law and driven by Tarzan. This project vehicle (see the build in Import Tuner magazine) needs more testing. This was the first time the car has seen the track since being modded. Modified Mono FLEX coilovers which Tarzan praised for making the car easy to control. Ran 2:02 – 2:03 in practice but had some gremlins come race day.

GMR Racing


S2000 – Unlimited FR (bumped from Limited due to mods)
Driven by Casey Dennis. GMR just recently installed the Super Racing coilovers. I am sure this car will go faster as they get it dialed in. Best Time 1:58

Have to mention that Sierra Sierra Enterprises broke the all time record with a 1:41.046. Watching the EVO carry speed and accelerate out of each corner was amazing.

A staff of enthusiasts

Posted on by

The TEIN USA staff is filled with automotive enthusiasts from different age groups, backgrounds and levels of interest.  Tuning philosophies, budgets and experience vary greatly but it makes for some interesting conversations. It also gives our product development section a chance to hear feedback from a wide range of opinions. Here are just a few of the staffs cars’.

Philip’s EVO 9 SE. Street/ track toy with the main goal being balance of all parts. Utilizes many parts in which TEIN USA distributes including Carbing, Defi, Takata, SuperPro and rocking Super Racing coilovers. Basically built/ tuned like a traditional shop demo car in Japan (trying something different than the normal US build).

Paul’s WRX. Custom valved TEIN FLEX with 8kg/ 5kg spring rates. Nothing crazy here but lots of bolt-on parts with total tuning in mind. Mainly a street car with an occasional track event.

Jon’s FC. A true do it yourself build including motor rebuild, tranny rebuild, paint and all the maintenance. Mono Flex dampers keep this a fun track toy while still maintaining good ride comfort for street driving.

TK’s Eclipse. Not the most popular model in the Eclipse family but purchased because this car was not offered in his home country of Japan. TK has previously owned an Integra DC2, JDM GC8, Skyline GTS-Type M, D32A, and Opel Omega. This daily driver uses Super Street dampers.

Ryan’s Civic Si 4dr. This daily driver features Super Street coilovers, Fujitsubo Legalis R exhaust, and a host of bolt-on parts. Ryan has been tuning his car on the local mountain passes and will be soon hitting the circuit for the first time.

N1 Racing parts on a street driven Civic Si Sedan

Posted on by

Mike of Evasive Motorsports has successfully been using our Mono FLEX coilovers on his street/ track Civic Si Sedan. The car has finished well in the last few events (class win at Super Lap Battle Finals 2009 and class win at Redline TA 2010 Rd.1) and Mike wants to keep it that way. Mike already added a larger diameter sway bar and a revalve but still wanted more vehicle rotation. So Mike and our engineer agreed the next step was to try some parts from our N1 race kit.

The parts arrived last Friday and Mike brought the car in a few days ago for us to install the parts and perform the needed revalve to make it all work.

The N1 kit is used on many cars competing in Japan’s Civic One-Make race series. Normally these cars use spring rates of 20kg front and 26kg rear. Modifications are very limited to keep the racing tight.

We ONLY used a few of the parts from an N1 kit:

N1 pillowball rear spring seat, Special 20kg rears springs, N1 HAS (Height Adjustment System)

The N1 pillowball rear spring seats are NICE (you can see that the top section can pivot). The spring can now better match the travel radius of the lower control arm and allows the use of a straight spring which are readily available in various sizes and rates. Normally a barrel shaped spring is used for more spring stroke but alternate spring rates are not available.

To make this all work we needed to change the stroke and damping force of the rears dampers. Then in order to balance the car front to rear we increased the front spring rate to 16kg, shortened the stroke, and increased the damping force.

The end result is very aggressive spring rates, short suspension travel and race car like handling. When we took the car out for a test drive on local roads and highways the ride was surprisingly smooth. A passenger would never guess that the car has such high spring rates. The car is firm but not bouncy. It absorbs the bumps well and settles quickly for optimal grip.

Redline Time Attack Season Opener

Posted on by

We want to congratulate Evasive Motorsports and SportCar Motion for their class wins in this past weekends Redline Time Attack held at ButtonWillow Raceway.

Evasive Motorsports campaigned two vehicles. Their well known EVO 9 in the Super Modified Class and a Civic Si in the Enthusiast FF class.

Driver Tim Kuo piloted the EVO 9 to second place finish with a time of 1:47.987 on Yokohama slicks. There is still lots of time left in the car and we will be working with Evasive to dial in the Super Racing coilovers.

Driver and vehicle owner Mike Chang pushed the Civic Si Sedan to a 2:04.085 for the class win in Enthusiast FF. Expect this car to get faster as we will be making changes to the rear Mono FLEX suspension (soon to be using parts from a TEIN N1 racing kit).

SportCar Motion debuted their Integra Type-R in the Modified FF class and driver Renzo Marsano not only took the class win with a 2.00.055 but beat the next top finisher by 4 seconds. The crew at SportCar Motion will soon be testing out new spring rates and new valving to make the ITR even quicker.
