Ok answers to hopefully most questions!
1. The SDW arms make the front end 4mm narrower in TOTAL, 2mm each side. They make the car a lot better to drive and give it a lot more positive steering with a spool, and indoors with a 1-way on rubbers it is unstobbale That doesn't make the std arms obsolete, I used them the other day at Halifax (for non UK-ers this is a huge track where the last nitro euros were held) and they allowed me to run a soft, progressive setup without to much bite to scrub off corner speed. Std arms seem better on more flowing tracks, very low grip situations (the team ran std arms at the stafford national, where chris took ftd and won) or in very high grip outdoor situations, I believe this is what the Jap team run, and hence why they come on the Masami Edition.

2. The yokomo springs. As they are progressive, there is no accurate way to give them readings as the poundage varies throughout the compression. The HPI springs have ratings, but these aren't entirely accurate. A 16.9 rated HPI spring felt very similar to a 14lb rayspeed spring on the track. The best way to match the new yokomo springs is in comparison with the hpi and then rayspeed springs.
The progressive springs make the car easier to drive and smoother, but these are the comparisons and conclusions I have come to: (I also asked Chris Grainger for some clarification ) These won't be entirely spot on accurate due to the different charecterisitcs of these springs, but it is a rough guide:
yok black = hpi blue = rayspeed green
yok blue = hpi silver = rayspeed blue
yok yellow = hpi silver/pink (in between) = rayspeed yellow
yok pink = hpi pink = rayspeed white
yok green = hpi gold = rayspeed red
yok orange = hpi white = rayspeed red/grey

with a 1-way, roll bars and std arms I ran yok blues all round (halifax)
with a spool, front roll bar and SDW arms I ran yok pink fronts and yok blue rears (stafford)
These were both with 450/400 oil

As an extra note, here is something I just made (see attachment). I believed more could be done in low-grip conditions than just removing the centre top deck post, and also saw that the team did this for the last Euros (well at least Pulmper/plumper did, can't spell it!), hence I got the dremel out and set to work
old top deck is on the right hand side for comparison

Thanks for the tip, could be handy to know in a low-grip situation

@mwoods: I think they are the same spring rate as the old Yokomo ones. Just longer.
Orange 18.87
Green 16.06
Pink 14.93
Yellow 14.71
White 12.94
Blue 12.12

Cheers
Chris

If you look here and notice the pulleys i think that you will understand what i mean , and especially the part ZS-630ASP

They're not BD pulleys. They're for the old MR4-TC.

Thats not the Masami section. Im not sure exactly what MD stands for, but its not Masami

Just look in the BD/SD parts section for Masami parts. I dont know id Speedtech has any listed yet though.

Ti Nitride shock shafts
White bomber belts
Ti screw set
new rear shock tower
new dogbones/cvds/unis whatever you call them
hollow centre shaft
precision bearing set
progressive rate springs

its all been discussed in the past, have a read back through the BD thread. Pulleys on the Masami are the same as the standard BD.

Smile SDW ARMS

You use the SDW front arms on the front of the BD. If you read earlier posts on this page from speedy 932 he dremeled a bit of the SDW arm. By having the front narrower it will give more steering.

Cheers
Calvin.

In the SDW arm set, you get a front and a rear. The front is 2mm narrower, the rear is just a std rear BD/SD arm with 2 holes. So you need two sets to do the car.
