isnt he a member here?

he says nothing that isn't true. you want to see plots then ask him.. maybe he will show them to you. his page doesn't say that you can't have good control with torsion bars anywhere. define superior. depending what you start with, yes you can bolt the system in (you buy it as a complete system), align it and bang you have a car that handles far superior then it did before. you want to spend 4k+ and shop all over the place for the proper parts for a torsion bar set ups then go for it. to me there is no way all that steering linkage will ever feel like a rack driving down the road.. like i said if you think anything is bolt in and perfect for any intended usage you can dream up you are just an idiot. and from what i've seen posted on various forums and facebook pages there is no shortage of idiots in this hobby..

Lol. There's nothing "superior" about the geometry, it's just marketing BS. Maybe it's not a lie, but it's not really true either. And really if there was anything clearly superior about the geometry those plots would be plastered all over the RMS website. Or even here! Certainly there's enough coil over supporters here that they'd have been posted if they were so great. The truth is more like splitting hairs, trade-offs and compromises. But splitting hairs doesn't sell coil over conversions.

And no one really talks about how those coil over systems load the chassis in a completely different way than it was designed to carry the suspension loads, because that affects handling too. It probably has a bigger effect than any difference in the geometry if it's not addressed.

As for the rack and pinion, it still amazes me that people are so bothered by the small on center spot you get with a properly adjusted worm and ball steering box and properly maintained steering components. A rack and pinion will not make you lap any faster, it's not a handling improvement. Maybe it's just because I grew up driving classic cars, but I don't understand at all why people are so enamored with the rack and pinion set up. I've never jumped in a newer car and been like "wow, rack and pinion steering!". Or maybe there's just that many people that don't know how to properly adjust and maintain a worm and ball steering system?

I'm pretty tired of hearing the "shop all over the place" excuse too. You can't handle ordering from 3 different places? If the whole suspension doesn't come in one box it's too hard to manage? I could order from @BergmanAutoCraft, @DoctorDiff, and Summit Racing and replace and upgrade every single component in the torsion bar suspension including all the brakes and have it be on par or better than the best you can get from RMS. Take you 10 minutes to order everything you need, tops.

Based on a recent article, the Green Brick has been in storage for 15 years but is slated to get a 6.4 in the near future.

Eh. I'd like to be excited by the prospect of seeing the Green Brick revamped again, but if Ehrenberg is still involved I doubt it will be half as interesting as some of the builds here on FABO.
