I only changed the lower control arms not the tension arms as it made the car harsh over certain bumps ,
Dropping the rear subframe ain’t that hard if I’m honest I would try the rear Arb if you have one sitting around ,
LSD is a great mod transforms the car in to a mini m3 ! Nice big power slides better traction etc but they ain’t cheap ! Nice having proper rwd tho none of this 1 wheel drive nonsense for me it’s money well spent.

Hello Mark,

It's the second time I read this about M3 tension arms (I guess TRW JTC1423 and JTC1424). Could you explain that a little bit more, please? You don't recommend the tension arms from M3?

What I read before was from Marco_Polo here on the forum:

23 and 24 give you stiffer bushes - more noise, vibration and harshness though.
26 and 27 give you the additional track width and negative camber.

You can fit either pair separately, or both sets.

The control arms 26/27 are great and have no negatives, but the tension arms are to stiff ,over rd Imperfections they are harsh and vibrate through the steering wheel not nice at all .

Really good to know! As for me, the 130i it's my daily driver :)
So I should go for 26/27

Anyway, I would like to know: which are the gains / pros of tension arms (23/24)?

The gains are more benificial under braking the stiffer bushes will give less movement when hard on the brakes, apart from that i couldn't feel any other benefit.

I believe this shows how much give there is with stock rubbers. Firming it up could reduce comfort, road noise. And increase load peaks, like hard braking and violent loss/gain of grip with bumps and potholes.

When the wheel moves like that, everything that is connected is influenced to some extent. And that is what we feel, that is messing up the alignment for a very brief moment.
