I've decided I'm not going to put the front anti roll bar on after speaking to Troy at NMS he says without the rear one I won't feel the benefit.
Can't really afford splash out on the rear one and get my suspension setup so will get NMS to setup the suspension as is and may think about buying the lot in the future.
This is the brand new Westfield Anti Roll Bar as shown below

I'm looking for £200 on it which is a saving of £73 on buying from Westfield and will go well towards setting my existing suspension up properly.
