A2 style hubs? bear with my thoughts.

[scirocco86@home.com]

I think I may have been misunderstood. 

A. Converting to A2 hubs and tie rod ends would eliminate lowered 
A1 bump steer from the tie rods sitting lower than they normally 
would. I snagged this from reading a 4x4 magazine and seeing how 
it's a problem on them. 

B. Converting to the A2 strut assembly with A1 upper strut 
bearings would possibly allow more suspension travel. Something 
the A1 chassis lacks . Or would it not alter the travel? I think it 
would.... My question is since the A2 struts are longer and the 
housings possibly different in length , would this upset the caster 
at all? Too much caster is bad, I like being able to turn and not just 
go straight..... Worse case scenario I try this on the project GTi 
with some junkyard A2 stuff. Would the A1 ball joints bolt into the 
bottom of the hub? 

C. I think we have it nailed that getting wheel bearings and axles to 
fit is not a problem at all, now we are left with seeing if it is going to 
have any negative affects on the A1 chassis front end. Most 
notably caster, since it's really not adjustable on macpherson strut 
cars. I can deal with the camber plates and crash bolts in A2 struts 
for the lack of bump steer in the A1 chassis. Am I just beating a 
dead horse here, or does this sound feasible and good to anyone 
else? 

D. I don't know, throw ideas out people, or criticize me and call me 
stupid.
