Rear Stress Bar

Does anyone have any experience with using a lower rear stress bar ? Essentially, this item bolts to the rear sub-chassis just behind the triangular stress plate. This product is designed to keep the rear camber in place and "tighten" things up a little bit better. I know that Mantis Racing makes a popular one.

EJ_2001_986_S is infamous around these parts

A number of people over at PPBB have put them on and IIRC the overall response is that it appears to work as advertised, no hard numbers to back it up though. There's 3 or 4 vendors of them, Mantis, Pedro, I think Schnell, they should be easy to shop around for.

Yep. Got one... I like. I do notice more precision from the rear of the car at traction limits. Useful for track or AX where you spend a lot of time at the ragged edge. Not much benefit for a street car.

Using a jack on it only managed to lift the car up, and the stud didn't budge.

If I remember correctly, I had a bit of time getting them out at first since I was holding back. A good solid whack dead on should get it right out.

(Try to loosen the nuts slightly first, then give it a good solid whack so that it moves... then remove the nut, and remove the stud/bolt out upwards from the top)
