I do still run a big bar in the back for now (034) but I have it set at the softer of the two settings. I did my coils in anticipation for the season, so unfortunately I haven't had the chance to test everything out yet since most events are cancelled. the 450/750 actually isn't bad as a DD, the plates suck (especially because these are no-name ones) over expansion joints but the setup is smoother than expected overall. I won't be jumping to "slicks" per say, but I'll be running 200TW. I'm sort of anticipating a spring change at some point, but I need to see how the bars / springs / tires play with each other first.
If I had seen the Verkline LCA before I did my coils, I'd probably be trying to find some OEM style top mounts to replace the plates and then do the LCA for way better adjustability. The only downside to those is that it still looks like you'd have to remove them to adjust the arm lengths (loosen jam nut then spin the heim joint)
Are you running with SCCA?
If so, the Verkline LCA is not legal for STH, due to the material of the suspension links.
14.8.B
Suspension bushings may be replaced with bushings of any materials (except metal) as long as they fit in the original location. Offset bushings may be used. In a replacement bushing, the amount of metal relative to the amount of non-metallic material may not be increased.
This does not authorize a change in type of bushing (e.g., ball and socket replacing a cylindrical bushing) or use of a bushing with an angled hole whose direction differs from that of the original bushing.
If the standard bushing accommodated multi-axis motion via compliance of the component material(s), the replacement bushing may not be changed to accommodate such motion via a change in bushing type, for example to a spherical bearing or similar component involving internal moving parts. Pins or keys may be used to prevent the rotation of alternate bushings but may serve no other purpose than that of retaining the bushing in the desired position.
As awesome as the Verkline LCA is, it breaks all the rules.
I emailed them to see if I could adapt just the lower offset ball joint to the OEM part, but they said you have to get the whole LCA for the parts to work.
I don't know why a company hasn't made an offset lower ball joint yet for the MQB platform.
