After years of setting records with our S55 and N55 “Lift Kit” camshaft products, we’re now releasing our Gen1 B58 “Lift Kit”. This is an absolutely game-changing product for the Gen1 B58 community!

Since the camshaft profile is OEM spec, this means there’s no need for upgraded valve springs or any special tuning. Install this with your Dorch HPFP and you get 40% MORE fueling capacity beyond our existing HPFP flow!

Gen1 B58 engines have two different versions of camshafts depending on build date. These two Gen1 engine versions have been designated as Gen1 and “Gen1.5”. The link below clarifies the 08/2017 build date cutoffs and which engine your vehicle is equipped with. As always if you are unsure on fitment, simply send us an email with your VIN.

NOTE: Once you get towards the upper limits of our DS25 HPFP, the B58 fuel system is very much limited by the injectors. In order to see the true benefits of this upgrade, you will need higher flowing injectors.

Very soft and comfortable
Color: Black, Size: 1 inch
I really love this yoga mat. It has the perfect balance of comfort and support, so it feels soft enough on my joints but still stable for workouts and stretching. It doesn’t slide around on the floor, which makes me feel more secure during poses. The grip is really good even when I start to sweat, and it’s easy to roll up and store when I’m done. I also like that it’s thick enough to cushion my knees and back. Overall, it makes my workouts more comfortable and enjoyable, and I actually look forward to using it.

As Advertised.
Color: Boysenberry, Size: 1 inch
The boysenberry color is pretty. The Retrospec mat is odor-free, 7/8” thick (so close enough), dense, and non-slip on my wood floor. I wanted the density to cushion pressure points whilst performing various core exercises and general stretching on the floor. It works well for my purpose. I agree with other commenters, the 1” thick mat is too unstable for yoga. That said, the slight instability makes this mat useful for developing balance and core stability by balancing on uneven surfaces, similar to the benefits of walking on grass or trails. The mat is easily nicked by long nails (human and animal) rocks, sticks etc. so pay attention to where you set it up; however not a deal-breaker for my use. I originally looked at the BalanceFrom GoCloud mat because it is the mat that appears in several online reviews with a link to Amazon. However, once on Amazon, I noticed remarkable similarities between the GoCloud and Retrospec reviews. I suspect both mats are identical just with a different brand name and sold by different companies. I ultimately went with the Retrospec mat because the Retrospec is sold and shipped by Amazon so the benefits and protections of “Amazon Prime”, including free returns, apply. The GoCloud mat could be returned however according to the fine print, if the return wasn’t due to Seller’s error the return might be subject to a restocking fee. One of the most objectionable review comments common to both brands had to do with the mat having a terrible, lingering odor. I was willing to take a chance and order it, but would have returned it if it had a bad odor. I did not want to pay a restocking fee so went with the Retrospec mat sold and shipped by Amazon. One exception is Amazon Prime offers the GoCloud in black only. I didn’t want black because I expect to occasionally use it outside in the Florida sun and it will get really hot.
