UNIbraces XB & UB - Review (UPDATED 23rd Oct)....

I'm not surprised that there could be some additional noise from the UNIbrace XB as it is tying the car together and like you mention as things get more tightened there is additional noise. However, the way you are describing it seems very unusual to me. Was the cargo net with metal fasteners attached when you had this experience? I'm just trying top figure out where the additional resonance could be coming from. Personally, I wonder that you may not have driven that stretch of road with the seats folded down. This coupled with the UNIbrace XB could be creating new sounds. Looking forward to your further reviews. Bruce

....I went out and tested it this morning, with cargo net still attached, on exactly the same stretch of road and the sound has gone. I have driven that stretch many times in the past with seats down and before having a XB.
I can only think that it may have been some kind of settling in. I also tried to see if similar speed on similar roads induced the sound. I'm very glad to report that the noise, which was a fairly major level, has disappeared. EDIT: I have since discovered that it's the road surface of just one lane of that stretch of road which causes that unpleasant sound.
I have to say that, contrary to expectation, I'm loving the XB effect and think it's exploiting my KW V3 suspension to my benefit. The car even feels more stable when having to change direction more suddenly than preferred - For example, for some kinds of overtakes on a narrow English road.

I was chatting with rectal rooter Janner Sy this morning about my recent Trackday and how the car handled.
He suggests I try a few wet sessions for further experience but I wonder, even though the turn in and grip was amazing on my car (despite my inexperience I felt really happy with it. Perhaps tweaks will be wanted when I get better) if you can go 'too stiff' especially in the wet with my levels of power
:popcornsoda:

I think I'd be wanting the shell as stiff as possible and the suspension adjustable enough to address the stiffness. I would have to agree with RR that the Xb makes it feel the suspension is working more efficiently...

What I want is someone to fit it themselves... and follow these instructions.
-------------
Jack the car up from the rear jacking point, ONLY one side (just in front of the rear wheel).
Raise the car so that both rear wheels are off the ground. (car chassis should be under torsion)
Bolt up the front of the UB, and tighten bolts.
Start to bolt up the back of the UB and take photos to show me how much its pulling the chassis into alignment. (or if you have means to measure it then that would be even better)
Then Ill shut up and leave you all alone. :signLOL: :signLOL:
E30Dom:
I would happily show you the alignment of the holes on the Xb, with the car flat one ground and then being jacked... When I get back from east Sussex I will, it's quite interesting... :-)
