Cheers all, thanks for the options!
Koni FSD's do seem to be flavour of the month and look pretty good to me, so I'll be getting them ordered shortly.
De-cat and possibly a supersprint back box are also on the to-do list.
BMC-CDA was a thing I was unsure about, seemed a "nice" thing to do not essential?...
Powerflex I will do, I had that done all round on the GTV and it was like a new car! At the moment the 156 feels pretty tight, but they will go in when needed.
Brakes are also short listed, currently looking at the Red-Dot offerings. Just putting stock rear discs on but will be looking at something better for the fronts. They're not going to last too long, that I can see already....
Jasons, I've already got 17" wheels with 215's, 225's might overhang a bit too much. I'll have to look into that. I have looked at the front mount intercooler setups, might be a bit too far for me and what I have in mind. Also living in Gloucester I noy sure I want to make it soooo easy for the water\floods! to get where I don't want it! The LSD I haven't looked into too much, what benefit would I get for that, would that only really be required for a big increase in bhp\torque? Going 225-250 I asume would need an uprated clutch, I've seen Pud's use of the CG (from memory) motorsportsw offering on ebay. Is that a pretty solid unit?
