Thanks for this Dave. I've actually got a set of Copper AE springs I used to run on the rear of my Yokomo, I take it they might be a little stiff though ...

I can only find the Gold and Silver over here in the uk at the moment, I assume the Gold is softest, with Silver being hardest (of the three)? How do they compare to the Tamiya springs (ie is AE Blue similar in stiffness to Tam Yellow) ?

Your using these with the EvoIV suspension though, right? Does that make any difference to the spring rate? or is it just a case of more options on mounting? I should be getting my set soon enough, although I don't think I'll use it straight off, but at least it means I don't have to shell out for the Alu rear hubs.
(Maybe I can stop spending money soon, along with the MRT-VX Pro I brought this week, gonna be a big CC bill this month...)

Finally I have one, more open question.

Having run the car at the weekend with stock wishbone mounts, I've now changed it to D/D on the rear (2deg toe with std hubs, right?) and C/A on the front (I brought the front A mount when I got the car). What sort of affect will this have on the car? I rember reading somewhere on here that the narrower front end (due to C/A) gives it more steering, whilst also providing -1 deg of inboard toe out.

How does this inboard toe-out affect the car? I assume it will affect it when the car has the suspension loaded, as otherwise it would be no different to the standard set-up right? (I usually run with 0 deg toe anyway).

Thanks in advance
Ed
About the springs...Gold is the hardest of the three, silver is the softest. Tamiya Yellow is close to silver. Blue is 17.5lbs i believe, and gold is like 20.

Default Hey Tarnjit

Im looking at racing at bedrock on wednesday so any tips you have on setup for your home track would be good to share if you dont mind.

Just got a package from japan with all the new 415 parts and two EVO IV kits

Ok, all you expert!!!

I'm jumping back into the hobby. I've blown the dust off my HPI RS4 Pro...yes, it's just a Pro, guess that would be a Pro 1. And although it still drives quite well, I want to update to a new chassis.

My research has narrowed it down to a choice between the HPI Pro 4 and the Tamiya 415.

I really enjoyed driving the old HPI Pro, and found it very durable so I'm leaning toward the new Pro 4...but, the local hobby shop has all but sold me on the 415.

Soooo, what puts the 415 above the Pro 4...technical details wise...

Thanks.

Wicked.

im more or less running cosgroves setup with a tiny bit softer rear end (shock positions) , CS22 are by far the best tire, if you havent got them then u may ifnd yourself a little off pace. sorex tires with a moulded work good too.
Ruduce the castor to about 4degree
Running about 1degree camber all round.
19t i was running the belts 1 looser all round with a bit of skip off the line but i will be running at 1+ from now on.

seeya at the track

oh and what about the suspension block Q I asked? Or did I answer it in my post?

(BTW it was about what affect running C/A blocks on the front does to the handling)

It should gives you a bit more on power steering. Make sure you remove the o-ring inside your front drive cups as this will narrow your front and o-rings will cause binding when cornering.

Chris, I honestly cannot feel the difference. But the white belts looks cool though (until they get dirty that is).

I had a quick look at the front suspension, and I can't see how the shafts bind, even when at full travel, and on full lock (i put the suspension through it's full motion)
I'll leave it in for now, but I feel it's binding, I know exactly where to look, thanks for the reply
