RRE Lightened Flywheel?

[Budget Tuner]

I want your opinions on this wheel, is it worth the $135?

NO! For safty reason and hassle of having to replace it down the road, I reccomend against using a shaved flywheel. If you must have a light weight flywheel go with an aluminuim unit.

For basic purposes, its worth it. You'll notice quicker revs, and the car will be more responsive as you are shaving rotational mass.

It can become a problem once you are making extreme hp, but until then, you will be fine.

If you have seen what a shaved flywheel can do to a car when it does break I doubt you would be recommending it at any power level.

There was a guy over on DSMtalk that had RRE's unit and pulled it off and it had a huge crack all the way through it and he wasn't making too much horsepower. I'm pretty sure he was under 300. It's only a matter of time before the thing would of totally given up and most likely killed the trans and engine, and possibly the passanger in the car. It just dosen't seem like the risk to to take for the few tiny benefits to me. But this is just my opinion.

Have you ever seen that happen to a full weight stock flywheel? I have.

Try giving Tym@Buschur racing a call, and ask him how his stock flywheel shattered inside his bell housing.

So now you won't recommend stock flywheels either?

Thanks you for emphasizing on my piont! If i stock flywheel will do it then why in the world would you want to make it more weak?

My point was... it can happen to stock as well. Lightening the flywheel the way RRE does it, doesn't result in less strength really. I mean, sure it does, but not enough to matter.

I just like the comfort of knowing that I have a solid flywheel in my car. So I guess it is up to the driver to decide weather or not to take the risk. But my personal opinion is that the benefits of a lightened flywheel do not out weigh my peace of mind.

From what I read on RRE's website the stock AWD flywheel has a weight ring cast around the perimeter. Will removing it reduce strength? How about smoothing out the casting roughness? Surely casting roughness doesn't add strength. If anything all the bumps and pits are stress risers. Smoothing them down would tend to reduce the tendency for cracks to start. I agree that removing too much material, especially on and behind the face would hurt performance, also because there would be less material to absorb the heat of a hard launch. I would think that uneven heating and cooling is what causes cracks. What flywheel would handle that best? Aluminum transfers heat better, so it would be heated more evenly. Chromoly is stronger, so it can handle higher heat differences better. If only there was some organization that rates the safety of flywheels for racing use.....

My friend's car used to have lightened flywheel. He used it for 4 years and didn't give him any problem. As long as make sure whoever installs the clutch and flywheel knows what's thier doing you should be fine. Installing these components are very difficult than other cars. If you're trying to save money for the mean time, I should say go for it. Then again, if you want to have it changed because you want your car to perform better, I say save another 200 dollars and you could get a fidanza aluminum. In that way you don't have to spend twice for labor just in case you're gonna upgrade it again for an aluminum. Fidanza weighs about 8 lbs. and a ligthened flywheel is about 14 lbs.
