As you can see its quality is great. The bar is aluminum making it pretty lightweight. The bar is solid and thus pretty heavy. The metallic end links are adjustable and very solid too. Just to have a general idea about sizes, a stock SiR or ek4 in Europe has 12-13mm rear swaybar. The Ek9 has 22mm and the DC2 23mm. So this is actually bigger. If you want to do things right you should swap front swaybar as well. The 26mm stock swaybar from EK4 or EK9 will fit just right and not spoil the balance. With the ASR kit you almost ''copy'' the R suspension set up. With good coilovers the swaybar will improove handling vastly, giving you a touch of the R versions.
I have it installed for 6 months now and i am very impressed by it (in combination with the front 26mm swaybar). The handling became extremely better, sharper turn in, almost no body roll. You can attack corners with more self confidence and more safety of course. In hairpins it feels in its habitat. If you are very aggressive you can feel the car turning in 3 wheels
Furthermore, slip angles have become less. In a weird way after installing swaybars bouncy ride has reduced a bit. The way it goes through patholes is very good and solid. It's like being in another car! The steering has also improved vastly! It has gained a lot of weight and information through corners and especially high speed ones.
At the beginning i was afraid of having oversteerish reactions and actually snap oversteer when lift offs or braking through corners. At the 90% of daily driving nothing happens! It's safer than before as there is less body roll. It doesn't only feel more confident but it really has tons of grip. Of course, oversteer will be there only if you push hard, lift off hard, brake hard, so nothing to worry about.
Some drawbacks of the kit, is that due to metallic end links you need to lubricate the area often, as if not you will hear plenty of bothering noises. This is the only drawback i can think of.
I am looking forward to trying this set up on track
