Give it a try.

I will probably in the future but trying to stay close to stock right now. I have a SC6 that is nearly stock and runs very well. It has the kit setup.

So how will the MIP pucks system eliminate dog bone plunge?

Can someone advise me on bang for your buck weight savings. I'm running stock 17.5 and need to trim some weight. It's pretty obvious that I could easily spend 2-300 dollars in lighter parts so what is the top 3 or so.

Light weight chassis, mip pucks system, titanium screw set.

Doesn't eliminate plunge just the friction. The plastic pucks slide nicely on the outdrives. Noticeable difference in performance. Probably the best investment one could make to a 17.5 buggy.

I am running the latest Kevin King MM setup with new drilled shock location.

I run the shorty and esc motor config myself and my buggy wheelies out the corner at times. Recently went back to mid and added a shim for anti squat (under the front hing pin holder), along with the brass weight on the rear of the bulk head.

What setup would you guys suggest running for a damp-wet track, low-medium bite.

Stock setup feel... egh okay, but hard to drive, and feels like you have drive it fragile. My friend said his car sucks up here, but at the other track it's on rails...

Would you go Zach Rogers setup?
I just put the RB5 arms on and it helped a little, but still not the locked in feeling I'm looking for.

Does the Lunsford Punnisher Ti Turnbuckle kit offer much weight savings? Can't find any information on it but seems like it should.

Yes the Lunsford kit would be another good weight saver.

Thanks. I can't seem to find how much weight it saves but it seems like it should be significant. The punnisher w/o the ball cups is only about $27 at amain. My stock build with shorty lipo is running about 1630g and I'd like to shave off enough weight to hit the mid 1500's to provide some flexibility to run saddle packs if I want. Also not trying to break the bank. If I had about $300 to spend it would be easy but trying to do it for around a hundred is much more difficult. Is 14g wire okay to use on a 17.5 esc/motor? That might be a cheap way to drop some weight as well.

What effect of any does motor size have on a setup? I mostly run stock 17.5 on sticky indoor clay and most setups, even ones with similar track characteristics use 7.5t motors. Just curious if those should get me closer still.

I run 17.5 but have the same setup as the mod guys: oil, springs, ballast etc. A good setup should serve well in both classes in my limited experience.

From what I understand, serious mod guys will typically start off with a 13.5 at a new track to make it easier to dial in their setups before switching to the more aggressive motor... so it shouldn't make much of a difference.
