Hi everyone -

My 415 is just about finished - the electronics are in and I'm excited to try it out.

I will be using foams with the car and would like to know if anyone has experience with a 415 with foam.

I realize the two one-ways are probably not the best with foams but I just run for fun and like a car to handle neutral.

Martin Crisp suggested I use Associated purple springs in front and copper in the rear. Except for adjusting droop and camber all the other settings I plan to keep stock as a baseline.

Any suggestions to any suspension adjustments that will help with the car's handling?

I hope to get it running by Thursday...

cheers

Dave

Hey Martin! Could you hook me up with the 19T spec set-up but 1 for use with Foam tires. I have an Associated Spring set not a Tamiyas one so maybe you could tell with those also.

Default foam setup

xcrazybenx

For foam racing I made up a front diff and locked the center one-way eventually. I started with the double one-way, but it was hard to be consistent, but with 19 turn it is not too bad wth the double oneways.

Here is a base setup

Front

Springs : Assoc purple
swaybar : Tamiya Blue
Shock Oil : Assoc 70
Caster : 4 degrees
Roll Center : (Moderate) Upper links have no spacers. Other than the anit-dive no additional spacers under the hinge pin blocks.
Anti-dive : 1mm spacer under rear hinge pin block
wheelbase : all the way to the back
camber : -1.5 on front left , -1 on front right
Tire : Speedmind 35/52 shore

Rear

Springs : Assoc Copper
Swaybar : none
Shock Oil : Assoc 50
Anti-squat : none
Roll center : (low) Links have no spacers on inner pivot ball. Used inner hole on rear upright. Hinge pin blocks both flat on chassis - i.e. no spacers. You might want to try a 1mm spacer under the inner pivot ball on upper link to make the rear a little more stable.
Rear Toe In : Total 1.5 to 2.0 Since it is a double one-way you may even want to try 2.5 it the car is too twitchy for you. I liked 2.0 with the double one-way and 1.5 with no one-ways.
camber : -2.5 on rear left, -2 on rear right.
wheelbase : all the way tot he back
tire : speedmind 35 shore.

Depending on the track I will run slightly more camber on the left side of the car. i.e. most tracks seem to have their highest speed corners turning right. So to ge a more even tire wear I add just a little bit more (maybe .5 degree) camber on the left side.

Yeah, pretty disturbing huh? It's the title of the song that plays when the chick in my avatar does something really cool in the anime series she's in (no spoilers). It's a pretty cool song and fits her perfectly

After racing my EVO III SE today it looks like i have at last given in and about to order a 415, not that the EVO III is a bad car but with the alloy gearboxes needed to free up the drivetrain it stands no chance getting near the min weight of 1500g.

Tips on locking up the centre and front one-ways would be very welcome , also setups from UK drivers that use the 415 outdoors on tarmac would be great.

415 ownership here i come

well, i did finally succeed in getting mine locked front and center. did the usual filing trick on the center, and used lots of Yokomo parts for the front diff... works great! let me know if you need any details on that swap...

I've tried several solutions to the one-way problem and non have provided me with the solution I'm happy with - I too was thinking of maybe jumping ship. But as I've already got a stack of EVO III parts, I'll leave the swap until I run out of bits. How many parts are common between the EVO III (Surikarn) and the 415?

I have a spool for my 415, but I'm lacking another center pulley to make the center locked. I guess once that's done, I can try that out.

I did run the 415 on carpet with foams. Seemed to handle pretty good with dual oneways on a low traction carpet track in stock class. I was basically using Mark R's LRP setup except with 1mm shim under rear camber link and different oil and droop settings.

Anyways, waiting for the rain to stop so we can go back on the asphalt!!!
