To suppliment the above i have fitted the MK4 R32 23mm ARB, there is a 21mm one aswell. The LCR OEM one is 19mm. The 23mm R32 bar and accessories were about £100 which is about half the price of the aftermarket ones.
I would advise you fit the 23mm front ARB, with the 28mm Rear Neuspeed ARB and the S3 strutt brace and see how you feel after this. Fitting this with new suspension is alot of money and might end up too much of a change for you
