Hj i bought this spring and i didnt install yet..... So the low spring put in front and the high spring in the rear right?

It fits, and it works. It is VERY grabby, this was expected though. The thing shift locks HARD when you want it to, and picks up off the line really well. I love it.

its a good exhuast cheap and quiet the only thing that i didnt like was the fact that it took them 3 months to get it to me

I took the exhaust system to a shop and they fitted it in almost perfectly, except that one of the pipes was rattling against the under frame of the car. Otherwise, the exhaust sounds mellow at low RPMs, and sounds nice and aggressive at the higher RPMs.

These springs were very easy to install and their performance is exceptional. On my Mazda 6I Sport, they ride almost like the stock feel with a little less body roll and a lot less squat. The car sits level yet it is about 2 inches lower than stock. I liked how the instructions that came with the springs clearly explained how much to cut your bump stops according to the model springs you purchased and the model car you are installing them on. I personally installed these springs on my Mazda 6 in 4 hours.Based on price, performance, and quality,I would purchase these springs again. Thanks HPF

I wanted to thank every one Branden, Chris, and Kirk who helped me with my purchase of my Short Throw Shifter and my Nitrous Kit. HPF was incredibly awesome while my nitrous kit was having some difficulties being shipped Branden and Kirk remember. They kept me up to date with shipping status and were so awesome on the phone while I was getting frustrated. I will continue to purchase my upgrades for my Roush Focus through HPF because of their amazing customer service! Thank you HPF!

This is a great product at a great price I have yet to install the coilovers and i still noticed a huge difference in cornering ability and stability of the overall ride. 98 accord

Very good first impression of HPF. After countless calls to other vendors I decided to give HPF a try. Kirk's attitude and helpfulness was the final factor in choosing HPF for my exhaust purchase.

The S3 short shifter is by by far worth every penny. Installation took no more than 20 mins, and shift stroke was noticeably shorter than the factory shifter. We all know that the C's shifter quality in unmatched but the S3 isn't far behind. This is highly recommended for anybody who wants a quicker response for that clutch to catch.

Had no weld on inside. outer welds were good. Fitting was a straight bolt on. Make sure you clean Headers before fitting or you will have finger print marks on the runners, permanently! as it heats up for the first time.

Picture did not look like actual part. Had to make extra bracket for cruise control with some other modifications to Hoses on my H22Z1.Maybe harder for others as I am a qualified mechanic. Good for intermediate and upper power gains

i have an evo 8 and this clutch works great! it enages very smoothly but clamps better than stock when driving and launching. i am very happy with this clutch set up.

Although i did not feel much power gain, this flywheel was easy to install and the engine revs smooth, i have an evo 8 and this flywheel lets me launch the car with ease. A+

This is an awsome computer. I can control almost any aspect of my car. I can't give it a higher rating because the software (Tuner v2.0) is not complete. There are features of the computer that cannot be used because AEM has not written the code or instructions. For example, Traction control is not supported by the software, but I know it is in there because I can see the guages that control the traction control feature. The software does not yet fully support the serial guage. (AEM said the next release of Tuner will fully support the guage). AEM support was very good. I like the comuter and AEM. I expect that they will continue to upgrade the Tuner software, which will unleash the full power of the Series 2 computer.

Easy install. All the wiring had plenty length. The response and accuracy is good. I use an AEM series 2 computer and have had no issues connecting the uego to the series 2.

Excellent power, excellent kit. I had a couple issues as my turbo was faulty but was replaced under warranty as well as my scavenge oil pump which siezed because of the turbo failure. All in all excellent customer service and I will continue to enjoy my stage 2.5!

Would highly recommend...I have emptied the catch can twice now in 3000km...probably should recommend checking it every 500km or 300miles...roughly every fuel up would be adequate.

great gauge pod, came to me primed and ready for painting, looks great in my 2001 wrx, easy to install, quick and easy delivery, a little more expensive than others, but I was happy to pay a little extra to receive quickly.

Easy instalation. Did it myself. Hardest part was getting the weight distribution correct and height even, but other than that it only took about 2hrs to install and the rest of the day for adjustments.My GC8 handles so much better now. The camber and damper adjustments are "easy peezy lemon squeezy"!!! For the price these coilovers are one of the best!

Great Exhaust system.i've had it on my GC8 for about 4 months now and no complaints. The can is a bit on the Big side. Not that loud at idle but sounds decent at Wot.. I wish it was a little bit louder but i'm pretty happy with it. Easy instalation. Probably took about 25 minutes.

Pretty easy to install. Sounds SICK when i punch it! deep beefy sound! A little bit of a difference on HP but not that noticable. One thing i like about the Secret Weapon Intake is the option to make it a cold air intake with the ducting and stack provided with it! Just ripped out the stock plastic piece in the fender-well and ran it down to the bumper and "Viola" short-ram to cold air! All in All, a Great addition to my GC8!
