Default HPI Pro4 VS YOKOMO MR-4TC SD SSG Special

Compare between HPI Pro4 and YOKOMO SD SSG, which one is far more better when it out of the box?

I saw the SD has a benfit of changing the Spur without removing the upper-deck. While the Pro 4 seems having stronger A-arm.

And also when i read the manuel of Pro4 , i saw there is a Front toe out of 2 degreed, is that true? wasn't that will slowing down the car on stright run!?

Anyway, can anyone give me the answer of the following question:

1. Which one is more stiffer?
2. Which one is more easy to mantanence and has fast easy to change parts?
3. Which one is lighter?
4. What if a SD RAYSPEED convenstion compare with Pro4 which one is better interms of stiffness, weight and mantanence?

AND 1 final question.

Which one you guys recoken I should by,
HPI Pro4

OR

YOKOMO SD SSG Special + Rayspeed convension Kit.

Hope some one can help me decide, Thanks!

3. Which one is lighter? theres only one way to find out

The Yoke will own the Pro4 IMO

AND 1 final question.

Toe out is adjustable....Toe-in will also slow you down on the straits

Get a Yokomo SD CGM Edition + Rayspeed kit instead....Cheaper AND you get all the graphite chassis componants instead of plastic like the SSG

Plus, you don't have to put up with a one-way diff if you get a Yoke...BTW Diffs take 3 screws to acess on the Yok..real easy to get to them

If you want an alternative, check out the Tamiya Evo 3...look for one on the buy/sell forums or ebay (thats where I got a killer deal on mine)

Pro 4 is ligher

you can't compare Rayspeed SD with hpi pro 4, the pro 4 would have to have bmi or PRP conversion.

HPI is a littler harder to get ot the diffs because you have to take off theupperdeck before you can open the diff cares.

Pro 4 is just the better car though. I beleive pro 4 has more room then the SSG also

out of the box performance has to be pro4 IMO cuz my friend had a new SD w/rayspeed conv. and i had a pro4 both first time racing them and the sd was having abit of a hard time in the corners, that could be tuned of course.

as for stiffness and weight of a rayspeed sd to a pro4, still the pro4 as when a tried twisting the sd it was nowhere near a stock pro4. as for durability the pro4 should be a little stiffer minus the oneway issue that could be fixed w/prp brace.

ease of diff exchange has to be the yokomo

so in the end i'd suggest a pro4
but you wont go wrong with either cuz the sd is 1 good car aswell, but considering to pay for a kit+conversion, hmm...

I'm still going with a Yokomo CGM over a Pro4....

It comes down to the lil things

Pro 4 Yokomo CGM
X X Parts
X O Ease of Matienence
O ? Stffness
O X Weight

This is all from what I hear and if I were to go with a new car I'd go with a CGM over a Pro4 mainly because if the pros can deal with the extra weight of a molded chassis like the Yokomo CGM then I can too. And it comes with a ball diff (is adaptable to more different track conditions than a one-way) Plus if you want to ever do foam or mod then the one-way is useless

Exactly as Black Kat says the EVO3 is a really alternative. This car really is easy to drive and setup and you can get one at Ebay for cheap. Donīt believe the guys who think the EVO3 is outdated or bad of design. There are some flaws but this is with every car. But if you have to choose between a SD or a Pro4. I have complains about both cars. But if the Pro4 would use blue parts instead of those ugly purple parts well .......

Besides the whole one-way fiasco and the fact they even included a one-way with it theres no probs I can see with the car....Need to take it out though (yet another damn week of waiting, this is really getting to me)

How is the Evo 3 an outdated design? If you wanna see an outdated shaft design (thats still competative) look at the TC3

i stopped running my SD because parts is a real problem here, the local yokomo distrubitor is worst that crap, and yokomo usa isn't too helpful neither

on the other hand the local hpi distrubitor here is pretty good and always have parts in quickly, and hpi usa is nice to deal with too
