I saw that on aj's racing. Do i need to buy that when i lower my S? Im lowering it this monday with just springs, but once it gets a little warmer out, im going to be buying probably the tein flex coilvers. So right now its not going to be too low, but once i get the coilovers, its going to be a little lower. Are these necessary to buy? Any info would be helpful.

 

no

 

I didnt think so....

 

first time i see a product like that

 

it's designed to alieviate stress on the joints and axles, but it's not manditory... think about all the super taikyu cars that have been racing slammed for years prior to this product being introduced...

 

Haha, comparing race car's that have things custom made and parts replaced daily to personnal street cars.

In a nut shell, I think the spacers are a must for heavily lowered vehicles. Reasoning: lowering the car in such a way changes the pinion angle (angle of driveshaft where it meets the pumpkin). This changed angle can cause added stress on this joint, the drive shaft, and the pumpkin causing premature failure. On top of that, the change in this angle has been proven to actually steal 1-4whp. So you be the judge of whether or not you find it neccessary.

FYI, I did extensive changes to the Race Car I'm on a team with concerning pinion angle by adjusting the top link of a 3-link suspension style. Since the S2000's suspension is not a 3-link, an adjustable top link is not an option, thus these spacers from J's Racing.

100% certainty this is incorrect. There is now way this has been proven. If your are using dyno's to measure, then anything under 5whop is well within the margin of error for the equipment.

 

Although our car was not dynoed proving this, they manual at which we were adjusting our cars pinion angle said that it was. And it makes good sense when you think about it. If you're doubtful I can understand, it's a mere amount of HP, but I can tell as little as changing from OEM or Mobil 1 75w90 to LE 607 can rob a few HP due to thicker fluid, but it's nothing noticeable. All that kind of stuff can add up, so I try to minimize the HP robbing agents that are applied to my car. Reducing the stress on your drivetrain is the number 1 reason behind using those Spacers I will say.

 

Haha, trying to seem like a smart ass on the internet...

The S.T. race series is near stock. You are not talking about Super GT where they can use pretty much any composite they want to so long as their power rating is still retained for their class. In most cases in S.T., even an intake snorkle like spoon produces for the stock box is illegal... thanks for playing though...

 

guy guys, keep it friendly......ok, i just had to do that.

Anyhow, from my my understanding, the most important factor when considering these spacers is what Highrpmek mentioned, the added stress and higher chances of early failure at the joints. (although, on a street driven car, providing you're not beating on the car, you shouldn't run into much of a problem from it)
