personally what id do is fit the anti roll bars first, before doing anything else so you can decide whether you think the tt arb is thick enough for your driving style and whether to go further to r32 bar, also youll need to setup rarb too
and i wouldnt bother with the lower front strut brace, unless you just fancy spending money
I thought the TT arb goes under the drive shaft...And that you could just use standard drop links?
Any Farb will be better and most likely noticeable over the stock arb. The rear one will be noticed most if you only put one, being the rear, on for example. Have it set on the least stiffest setting first I were you and then stiffen it up if you require.
adjustable droplinks will be required for farb. and depending on how he sets up the rarb then the front may be killing the handling, throw in the tyre change and suspension and you have it a lot more difficult for a non pro to setup.
adjust/change one thing at a time to see if it helps or hinders
also i disagree about your rarb comment, they are the best thing you can add to any front wheel drive car, does wonders to reduce understeer, mk4s seem to benefit more from them than other cars thanks to there stiff chassis
