Yeah he's right... I appreciate the technical advantages of the S13 over the S12, but the S12 needs more acceptance and appreciation.
Also, if Sterling has his way, the multi-link won't be a hassle to switch to, he thinks he may have a much simpler way that doesn't require a lot of modification. If so... it would mean an S12 chassis could run with front AND rear S13 suspension goodies. Which would render the S12 as the better choice (after modification).
