16v - 8v suspension

Post by spigven » Wed Sep 07, 2005 12:57 pm

I was wondering what the differences are. I suppose the obvious things are different spec spheres, thicker ARB's and wheels and tyres. But are there other differences ?

No. - except for the different pump - same spec - different fitting.

Brakes are the same for all BX including pads except for ventilated discs on front of 16 valve and consequentially wider calipers.

ARB's are the same on all from 1.4 to the 16V via the TD.

I was always told the 16v's had thicker rear anti roll bars?

I'm at work and so can't verify this but I'm sure that there are many variations of anti-roll bar thickness used on BX and I believe that the later 16 valves had thicker ones than the earlier ones. I think this is mentioned in Haynes.

Its not just thickness that are different either there are a number of different shapes! The 1.4 engine in the St Tropez has a big 'U' shape in the middle of it to allow clearance for the exhaust (which goes under the engine!).

From what i have seen its only the later 16v that has the thicker ARB and i would assume the earlier ph1 16v has the same ARB as the 8vGti.

Other than that the only other significant differences are the spheres as mentioned and the drive shafts (though i doubt the drive shafts are a real suspension issue)

I think the driveshafts are shared with the TD and may be the same as an 8 valve with ABS. The andyspares or eurocarparts on line catalogues may resolve this point.

Front ARB is either 22.5 or 23mm with either 135 or 145mm lever arm depending on BX type.

Rear ARB can be 17, 18, 19mm depending on BX type or 21mm for the later 16Vs.
