Me too. I understand cars like the Barracuda, you have to buy parts to allow the use of foams since the camber link is higher up than the tire itself.

I cant say for sure, because I havent mounted a 28mm rim on my MS, but with a 24 it looks like there would be plenty clearance with the stock LW parts. The only problem I can see would be the front spindles hitting by where the steering ballstud is. I have the Square spindles now, and they have an inner hole, I could use that and then grind down some of the outer material.

GT Racer, I posted my carpet/foam setup on page 213. Gonna try some different caster blocks his Friday. And also gonna try a softer spring setup. I didn't quite like the Copper/F Gold/R setup too much with Parma Foams. Seems like the car leaned too much. And if the grip got too high.. the car would traction roll. Yellow/F and Copper/R seemed better. But I'm gonna try again this weekend...

I have been playing with the stock 415 (not MS) chassis flex a little and looking to see how my laptimes were affected. I run a medium soft suspension setup on my car. I run #3 pistons all the way around with 50lb Associated oil in all 4 shocks. I run the Associated yellow springs in the front and an Associated purple spring in the rear.

When I was first searching for a setup, the car was great in stock trim (I am running a front diff and the locked layshaft pulley). I was a little faster with the 415 than I was with my TC3 and an incredible amount more consistant (I find this great considering that I ran the TC3 for three years and only have about 50-60 packs through the 415). The stock upper deck always seemed a week point to me however. Take it of the car an twist it. It offers almost zero support against twisting. Take the upper deck off a car with a 3mm chassis and you might not notice that much of a difference if you try and twist the chassis (IMO). Because of this I ended up gluing 2 top decks together for the added stiffness. The results were amazing. The stiffness of 2 decks seems 500% stiffer than the one deck alone. You go from being able to twist the top deck without even trying (1 deck) to having to exert force to try and twist it just a little (2 decks). With the top decks glued together my lap times were even fast and I was even more consistant than with one deck. The car seemed to handle much better as well. It also seemed with the 2 decks I was able to run a softer suspension setup.
For my driving style the 2 upperdecks works best. The chassis is a rock and I have never experienced a tweak problem. Considering that I am faster with a stiffer chassis setup, I wouldn't even want to imagine how the MS would perform on carpet with foams since the main chassis is thinner than a regular 415.

I hope the MS will end up working for you on carpet!

Randy on the Square hub use the rear ackerman hole on the knuckle, the front offers too much throw and scrubs corner speed way too much. You can tune some of it out with EP adjustment but it just does not work 100% correct. With 28mm foams on the front you are also going to need the 6mm hex along with 2mm of spacing to get clearance. You can cut down the width but you are losing footprint when you do.

Another mod that helps is to ream the outer hinge pin to 2mm and use the old c-hub, knuckle and axle(w 46mm bone). All of this helps get the front narrower without the scrub radius penalty of the all the hub spacing. Also just kiss the top of the C-hub with a 1/2 or so drill bit, this is so you can use the kingpin from the LW suspension fully tight. It also changes front roll center just a tad.

Again all of this is to help it work. I spent about 4weeks trying to get comp laptimes with the LW suspension. The gauge was Cartwright from Schumacher. The car was consistently .9 off the pace with the LW. I finally reverted to the original suspension and immediately the car dropped .6/lap with some minor changes I was able to get it within .1/lap. It also is amazing how close the Schuie is to the 415 all the positions, locations weight dist are all within 1-2mm of each other.

Default HELP!

Hi guys

My name is Andy and Im from New Zealand. This is my first time posting and hope you guys can help me out.

I own a TRF415MS and I had a little crash that broken the steering knuckle (Part#51103). I have searched everywhere on the net and couldn't find any spares. I have visited my local hobby shops but they told me to wait for about a month as the part needs to be ordered.

I couldn't really wait that long and wish to put my 415 back on the track asap. It will be great if anyone is willing to lend me a direction on where to buy them on the internet or if any of you guys have got a spare set willing to sell to me. I will pay for the frieght of cos.

Thanks again. Great forum, Keep it up!!
