There are a number of threads on this subject, a search would be worth while. But it boils down to what you are going to do with the car. Is this going to be a daily driver that you want to improve, going to the track a little or a lot, autoX? However, if you want to start slowly and basically use the car as a DD go for a 19 or 20 mm rear sway bar (probably 20 mm given what you have now) and camber plates - highly recommend the Ireland fixed plates and Whiteline 20 mm bar. This will give you a great street car and a very competent car for casual tracking and autoX. Another overlooked item is light weight wheels. This reduces unsprung weight which inproves ride and keeps the wheels planted on the ground. Would not recommend the 25 mm bar. The 25 mm bar is the same stiffness as the 22 mm bar but, being hollow, it is noisy and because it is larger it is harder to install. Both of which are probably too big without other mods (shocks, spings, adjustable camber plates...etc) because of the added overstear....That's my 0.02

 

Thanks Eddie

But I will research --- thanks again...

 

Here is a thread for a "free" change that will make you think your car just had a make-over :

You or any shop can make the change but you will need a wheel alignment afterwards to correct the toe-in
