tuure- Yes and Yes. If you run mod you might want to run double pink fronts, however for stock its a little too much scrubb in the corner and you can acheive the same steering with a dynamic strut front end.
grump- The only adjustment you can make on a dynamic strut that you really would actually do are front springs and maybe reactive vs. static castor blocks, but very doubtful. On the old school you can adjust caster as well as front springs. Before you say "wait!" let me explain:
-the strut front end is molded very poorely. In order to make sure the castor is equal on both sides it is very common to have to use lets say two shims in the back on one side and one shim front and one shim back on the other side. So you really cant adjust castor because you already maxed out the adjustment on one arm trying to make it even with the other. I have heard that CRC machines their own dynamic strut peices so thats why maybe when you look at their driver's cars it might appear different. However, obviously they are NOT included in any of their kits.
Also i cannot emphisize enough how much work it is to correctly build one of these front ends... Normally out of the box everything binds, so you need to ream out pretty much all of the pivot points, polish all of the metal pieces (i actually had to dremel some of the upper arm hingepin every once a while to get it to work smoothly), and properly set caster (using an RPM camber guage just look at the kingpin from the side). However, they do not stay well build for that long and require alot of maitence, also they get out of tweak and other fun stuff when you hit things, its not a good front end at all for someone just starting out in 12th scale, the old style front end is so much simplier, easier, and more consistant, and has just as many things available to tune as you could ever want or need.
As far as parts, the stuff you break on a 12th scale is normally stuff that AE makes, not CRC or Speedmerchant. You dont break a chassis (Sometimes if you dont prep it right you might split it a little, however that can be repaired with super and a clamp), or any parts that are specific to one car. As far as lowered bulkheads, you arent doing yourself a favor. The tire needs so much foam on the tire to be accurately classified at that shore rating, if there is not enough foam it will not be a grey anymore, but something much harder.
I am sorry if i missed some things... But i have posted on this topic ALOT over the past few months, however I realize its impossible almost to use the search feature to find stuff since the thread is so long, lol.
