Very good product, well made with easy instructions to follow. Installation was a breeze. One hose was slightly to short but that was nothing major. Highly recommended product.

The aem gauge was very simple to install. The hardest part of instalation is welding in the o2 bung.

Install way very easy. Could use longer bolts for mounting it onto the CAT. I did see a improvement in acceleration. It is the product and good quality I expected. Its quite but is loud enough in the top end to be noticed.

simple and easy to install. huge performance gains, especially when negative camber is desired

Professionally installed, there is some chatter on engagement, very diff feel to OEM, lighter pedal. Bite is good, no slippage holds pwr well on lightly modded M5. only 6 because just run in (500k), if stays together I would rate higher. Overall pretty happy, OEM always slipped, has truely transformed the car into a real animal, chatter at low speed engagement is acceptable for the overall performance. Happy and would recommend.

The parts themselves are very well made. The rear sway bar was very easy to install, the front however, is a different matter. It is not installed in place of the OE sway bar. It goes underneath the subframe and control arms and works WITH the OE. I was only able ti figure this out after contacting HPF and ST and receiving a diagram on how it is installed. But now that they are installed, they work great. I have no body roll what so ever.

These springs prove to be a superior product for their price. A perfect product for any non-serious racers that like to have fun but need a little give on those bumpy roads. The only downside I can see these is the ride hight when driving over sharp speed bumps, one has to take them sideways. This is true for any lowering springs and new buyers have to consider that such an installation will limit the amount of terrain capabilities that they can drive on.

The instructions where not very clear as to use the resistor that comes with it or not; other than that installation was a breeze once into it. Noticed an increase in acceleration, plus it's the first thing people notice when you open your hood!!! Note: when installing you have to extend the factory ignition wires and check voltage output if you have the wires hooked up wrong the readout

Good quality, works well, kinda a tight fit though if you're using a PWR radiator and stock 1jz intercooler piping. Cools off the radiator quickly though, and works well once the temps start trying to climb. :)

Part is installed and working as expected. No problems were encountered either installing or using this part. My thanks to the entire team for their help. thanks

The clutch has amazing clamping force. You can ride the clutch in first gear but it takes practice. It will stall on you if you are careless. For a street clutch i will rate it a 7.5 in the drivability department, only issue being coming out of 1st. Everything else is perfect. But for racing and having fun at WOT its a solid 10. Pedal feel is stiffer than stock, a bit more than i liked, but its not to bad, maybe like 15-20% more. Overall im happy with it. Maybe the best priced twin disc. Best part is the replacement parts are available in the US. No need for long shipping time and high cost.

This product was very easy to install. Clutch pedal feel is great, would never know that its a stage 2. Absolutely no chatter quite engagement and very smooth operation.

The product performs very well, it wasn't that easy to install but I was only stumbled for a couple minutes then got back right in. It's still at a comfortable height and love how quick it gets into gear when I need it.

I easily installed the adapter and worked great. The only thing I would have changed is the finish (the way it looked) even though it was mostly covered

Quality is not comparable with Y-Pipes from other brands like HKS, Tanabe or Fujitsubo! But the price is much lower and you will get a PnP Pipe with acceptable quality!

Great Product. Had no problems on installaion. Notced a power differance esp with a tune, but a tune isn't needed. Much larger and free flowing than stock or other tube type outlet pipes.

Bought the ATI Dampener to replace my OEM. Installation is straightforward and performs well. Please remember if your buying the ATI for the 93-98 2JZGTE Supra TT, you'll need to get a different belt. The OEM belt is not correct for the ATI dampener.

Peddle effort is less than the OEM pads and dusting is greatly reduced. I'll use EBC Red Stuff on my next brake job as well

Bought this radiator for my 98 Honda Prelude since my stock one was busted. Install was so simple and easy. Cooling seemed to be better than the stock one and it just looks awesome. I'm pretty happy with my purchase.

Good, sturdy filter, gives my engine a meaner sound, and a little better acceleration
