So I was the guinea pig and bought the Truhart Rear Camber Arms. Disclaimer: I reached out to the company and they offered me 20% off to try them out. I paid $145 vs the $187 common retail price.
General Impressions: Well made, good adjustment range, a bit heavy.
These are steel arms throughout. All of the parts are ferrous. They are nicely painted with no exposed metal except in the threaded areas. Threaded areas have a light oil coating. Threads have a mark on them indicating maximum extension length which is a nice touch. They include a bracket for the hole on the tab that is on the stock arm, but they can be removed. This hole wasn't used on my car.
Weight per arm: 1050 grams. Stock is 870, MPP is 610
Weight on fork end (estimate of unsprung weight): 530g. Stock 415, MPP 340.
The adjustment range is good. I can get about 3 degrees more camber than stock with them at the shortest position. They extend well beyond the original length too if reducing camber is your goal. They have beefy flats on the adjustment tube, and I had no issue changing camber with the suspension loaded. When unloaded you can just turn it by hand. I didn't notice any change in camber when I locked down the lock nuts.
The rubber busing is smaller than the stock bushing, and appears to be stiffer overall. I have no way to evaluate the quality of this rubber, but there are no immediate visual issues.
Fitment was fine except for one minor issue- the paint made the holes in the "fork" slightly too small for the shoulder of the bolt. I have contacted the company about this, and they are revising their design. All future parts sold will be updated. The company was highly responsive, replying to emails in under an hour. They are sold by a company based in the USA, and arrived in two days from order.
Overall: They seem to be a good value for people that aren't looking to save every gram on the car, and maybe would rather save some money for more seat time or other weight savings. Performance should be similar to the stock arms, maybe slightly stiffer due to having less rubber.
Tip: Place the new arm next to the stock one and you can set it to exactly the same length as the original and maintain your alignment. You can use the bolts from the car and drop them through the holes to get the length dead on.
FYI: These also appear to be sold under the "Hardrace" brand in other markets.
