Why you should buy this item if you own a 350 Z
100/100 100% if you have a HR motor with a bad stock clutch, I highly recommend this purchase. Your car will drive & perform better than new if you properly install this item.

500whp and 550tq single big turbo
Can confirm clutch will hold 500to the wheels have about 5000 miles on it still feels good don’t feel any slippage from the clutch yet so far so good clutch does break in and dosent feel as “grabby” after some time and makes it easier to daily if that’s what you want it for will not feel like stock honestly for the price point and the power it handles if I have to replace it once a year it’s great for the price

Works fine for me, I used a OEM throw out bearing.
I have put 30k miles on this clutch since December of 2022. Lots of Highway miles and lots of hard clutch drops in-between gear changes. I chose to not use the throw-out bearing included in the kit because I personally recommended to use the OEM ones. I have no complaint and their is no clutch slip, the previous clutch I had 70k miles was only swapped because my throw out bearing failed because the rear main seal leaked oil into the transmission bell housing and still had plenty of life left of the same style.

and 1 month in it seems to be a great option for the money
Been dailying my 350z with this clutch for about a month now. I had something come up and needed a clutch immediately and didn't have $1,000 for an exedy. Took my chances with this one, and 1 month in it seems to be a great option for the money. After about 500 miles it feels decent even for daily driving, but still engages a lot harder you just get use to it. I even raced the same night after I put it in earlier that day. 10/10 would buy again if on a budget. Not sure if it will actually hold the 580ish whp that it rates but for 300-350whp it's solid so far.

Exactly as described. Well Packaged. Great Customer Service
The items arrived as described in a well packaged box. The quality, dimensions and workmanship were as advertised or better and the couple of interactions I had with their customer service was amazing. I will definitely purchase from the seller and this product specifically again. Comes with a warranty as well!

It dries differently from a normal clutch because this light and fast takeoff.
What I like about it it was all there in the package than what I ordered and it was on time very fast it’s been about a month or two and it’s working just fine very happy.
