Posted on here before about this issue with no definitive answers, most common sort of answers I got were track rods not being long enough and driveshafts falling out due to not being long enough.

Well now I have some answers....

Yesterday I was working on my car when I realised the rear bushes on my wishbones were going and the n/s ball joint had gone. I had a pair of 20vt wishbones in the back of the garage with bushes and ball joints in good nick so to save money decided to fit them. When everything was bolted back up straight away I could confirm the driveshafts WON'T fall out and total front track increase is 49mm or nearly 2 inches!!! My coupe alloys now are no longer burried in the arches, with the tracking unchanged the car had massive toe-out of around 5-10 degrees and was massively unstable and undrivable even at low speeds so some adjustments were needed. After around an hour for set, test, set, test...(I have no tracking gear so do it by eye and driving feel) I got the tracking reasonable with slight toe-in and the difference is amazing!!! So much more grip on turn in and mid corner making the bravo like a go-kart, no understeer, this was all done in the wet when grip levels were low anyway. Stance wise the car looks a lot more purposeful now with the wider stance and with some negative camber on the front just improves the look.

The only thing I would suggest is a set of longer track rod ends, although the standard ones will reach I don't think there is much thread left on them so some longer ones will have a slight strength increase and reliability but alround simple to do and effective, I will uploads some pictures when I take some.

Cheers fella's....
 
Will get some when I sell my old Brava, after inspection I think they will be ok as long as the car isn't kerbed or a deep pothole is hit, just need to find out what track rod ends to use, so more homework is needed, when I get on the pc I will upload the photos although there already out of date cos last night I adapted the 20vt front suspension onto the 1.2 hubs, fitted the rear suspension and adapted the rear brake discs to replace the rear drums using the 1.2 wheel bearings to retain the abs but I think I will write a thread soon on my car, current mods, issues and future mods with abut more info on it but all is working well
 
Erm I imaging you'll have a load of negative camber on the front aswell now, that will account for the cornering grip but it will wear you inner edges of the tyres. Just keep an eye on that as negative camber is not a problem per-se but bald inner edges will make wet weather stopping a problem.
 
Yh I did go through one set of 5mm dunlops in about 400 miles but during that time I played with the toe angle to counter balance it and all is good, it does gripmiles better now initially but without the falkens I normaly run the top cornering speed is still a little slower buy about 5mph, also all but one tyre on the rear are Dunlop, the I'd one out is a cooper on the rear so I'm finding the rear grip a little out of balance at the moment
