Stage 1: Street, Drag, Drift, Road Race, Rally, Pulling, Autocross

Stage 1 Clutch Kits feature an integrally molded carbon Kevlar-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally bonded steel backing for strength under high clamp loads and temperatures. The hub comes in either Sprung or Rigid and is application dependent. The double sprung hub features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Best for street and many track/off-road applications.

Stage 2: Street, Drag, Pulling, Autocross

Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub comes in either Sprung or Rigid and is application dependent. The double sprung hub features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Best for street, drag, pulling and autocross.

Stage 2+: Street, Drag, Pulling, Autocross

Features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the 2+ offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity. The hub comes in either Sprung or Rigid and is application dependent. The double sprung hub features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rally and drift.

Stage 3+: Street, Drag, Pulling, Autocross

The flagship stage for a high powered street or race car that requires a manageable and friendly engagement, the stage 3+ features a carbon semi-metallic full faced material that offers unparalleled life, friction co-efficient and drivability characteristics in one single package. The hub comes in either Sprung or Rigid and is application dependent. The double sprung hub features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Great for street, drag, drift, autocross, road racing, pulling, rally and drift.

Stage 4: Street, Drag, Pulling, Autocross

This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rally and drift.

Clear Skin Staple—Gentle Yet Effective and Pairs Perfectly with My Favorite Facial Pads
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
This toner is my daily go-to for keeping my face in check. It’s gentle on my skin but packs a punch when it comes to keeping my sensitive skin clear and fresh. I use it every morning and night, and my skin has never looked more balanced. It doesn’t sting or dry me out, and it layers beautifully with my other products. Total game changer. I use Thayers Blemish Clearing Toner with the ForPro XL Facial Pads and the combo is perfection. The toner glides on smoothly, and the pads help distribute it evenly without soaking up too much product. My skin feels clean, refreshed, and noticeably clearer. If you’re looking for a refreshing, non-harsh toner to add to your routine that’s simple and effective, this duo is it!

Gentle, yet very effective
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
I've used multiple exfoliating toners in the past but none were as effective as this one. I have been using it for 3 days now along with the La Roche-Posay Toleriane Purifying Foaming cleanser and it's cleared the whiteheads on my chin quite a bit and made my face feel and look smooth. Will continue to repurchase.

Finally Something That Works For Me
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
Imma be honest - I haven’t had great skin for over 30 years. I feel like like there’s always :something: that makes me resort to only being comfortable wearing make-up any day I have to see people / leave the house. But, I started using Thayers in October 2025 (I created my own “Thayers system”: salicylic toner, salicylic pads, and - at times - the stuff in the little dropper bottle) and I can honestly say that :finally: something is working for my skin! I have tried everything! But Thayers is it for me these days. Thank you!!

Great product with unexpected results and skincare benefits
Size: 25 Count (Pack of 1)
I have been reading about Micellar water products for a couple of years, and finally purchased these wipes to try. I am currently working very long hours and the selling point for these wipes was that they weren't soap-based, and didn't require a toner after using. I keep them on my night stand and take my makeup off with them prior to going to bed. (I do not use them for removing mascara - I use another product for that.) The biggest point I want to share is that I have been using these wipes exclusively for makeup removal for a little more than two weeks. I have had a stubborn blackhead on my nose for a good 20 years that wouldn't budge, no matter how often I used exfoliating products, and I've invested a lot of money in high end exfoliators in an attempt to make that spot go away. It has grown larger over the years, and was a skincare peeve of mine. I noticed a couple of days ago that that blackhead is beginning to break down and get smaller. I thought at first that I was imagining it, but that blackhead is honestly a good two-thirds gone. This is just from using these wipes! I would never have predicted that something this simple and quite soft and insubstantial as a disposable face wipe would have such effective results for blackhead breakdown, but they're doing the trick. I have noticed smaller blackheads on my chin area are also melting away. I predict that in another few weeks of use, my skin is going to be as close to blackhead-free as it is humanly possible to achieve. (For the record, I don't have a lot of blackheads - just a handful that have taken up residence over the years and refused to budge, getting larger with age.) These are safe for my sensitive skin, and have exfoliating benefits that I wouldn't ever have expected or predicted. Full disclosure: I do spend a good 3-5 minutes using a single wipe on my face, neck, and décolletage, scrubbing with the nubby side (there is a nubby, exfoliating side, and smooth side to each wipe) and using the whole cloth in sections until I have used it all. Finally, I also use it on the tops of my hands. I definitely get my money's worth out of each wipe! I wholeheartedly encourage people to try this product. I now have it on Auto-Ship status, as I don't want to ever be without these wipes in my skincare arsenal.

Cool and moist
Size: 1 Count (Pack of 2)
I had to get away from scented products and this one was cleared by my ACDS app. It is small, not resealable, but easy to use, and cleans well, the wipes are sturdy, and just wet enough to clean without needing extra drying. These are travel size and have to be kept in a zip lock after opening.
