Very interesting thread; taught me a lot, so kudos to the OP and thanks for the post!

However (check me if I'm wrong), it sounds like the gains are to be had by replacing the guide and toe rods and leaving the upper arm alone. Using the M3 guide rod is a no-brainer since the length of the M3 part is the same as 135 OE. What options exist for the toe rod however? The OP has made his own, but are there off the shelf options for those not quite so talented as he? Any recommendations?

Also, it's mentioned that replacing these two parts will result in a rear spring rate reduction of ~23 lb/in. How significant is this? For example, I'm running Eibach springs in the rear; what percentage of my total spring rate would this add up to? 5%? More? Less? Did I say how awesome this post was?

Thanks for any info,

ianc
