bad advice, poor advice, whatever you want to call it, I see it all the time others saying, things don't fit, its all wrong, my question to the OP(original poster) say you cant fit it on a stock frame and you lose turning radius is "Did you try?" and "if so, what didn't work and could it have been fixed or done differently to, did your rim have the wrong offset? wrong steering arms? different camber or castor? for example after I installed the tru-trun I had the same steering in one direction and not the other, after looking at all the parts and cycling the steering over and over I found with manufacturing tolerances +/- whatever they are the steering arm stop hit a 1/2 earlier on one side than the other(could have been the 40+ year old frame angle, lower control arm mounting holes, whatever) I simply ground the steering stop down for clearance, same steering and now better ackerman

yep sorry about that off the shelf Coys model C55, 17X9.5, rear spacing 5.50", offset +6mm, Bore Dia 78.1mm, bolt pattern 5-120.65,all four corners

The bottom line is that the clearances are too close to make blanket generalizations unless you err on the conservative side. Also, some people have different definitions of what rubbing is, I believe it means taking the spring out and cycling the wheels side to side with the suspension BOTTOMED OUT. Some think if the tires only hit in extreme maneuvers all is fine, and that is ok, as long as everyone understands the situation. An extremely important factor is the camber that is aligned in. An autocross car that goes through a couple of sets of tires a season, isn't worried about -1.5 degrees or more negative camber, whereas a 100% street car isn't going to run near as much, and that extra camber from tilting the top of the tire in helps tremendously in letting the tire and the top of the fender get along.

yes my suspension was also cycled, that should be a standard thing to do when building (I'm no expert/engineer/designer just a hot rodder telling others what I have done) in fact I have a cool little test stand made from and old frame (cost me 50 bucks) and a old creeper, I try everything on first and measure....here it is with the tru-turn, DSE upper arm and stock lower arm
here you can see I'm trying Hotchkis springs in the setup, along with coil overs and several different spindles
and to me rubbing is rubbing and any friction between the tire and any surface other than the road is unsafe, I run 1.2-1.5 degrees camber(daily driven), my inner fender well is modified as shown in my build thread after the car was painted, I did it with a cool $19.95 harbor freight brake and scrap aluminum

probably not, I did a lot of testing on my own, crazy stuff, I even had extra steering arms that I heated and bent to run larger rims and fix bump steer, I cut lower control arms to add more castor and fix ball joint angles, Man, I have enough, extra suspension stuff that I have bought over the last 4 years, that I was able to build a custom suspension on my girlfriends 1963 AMC Rambler wagon and I still have enough to build another car+

agree, but my issues was just don't say it cant be done, that bugs me because 6 years ago I bought my car asked question and was told a lot of stuff on forums that I went ahead and did anyways and found out that many of those giving advice were wrong, WAY wrong, and a few companies that i have been around the last few years actually listened to a little racer guy like me
hope it all helps
