what's the pro and con of this car? I read a few pages back and there are people having tweak problem and breaking a-arms. Is there a fix yet?
what kind of "must have" hopup does the car need?
I have not broken any arms yet and the tweak problem isn't much of and issue for me since I countersunk my upper deck. I am going to go one step further on this and make my own upper deck that is countersunk and it should make the car a bit stiffer.
The car is great out of the box IMO and I have run stock, 19t, and mod with it so far. After everything, I have only broken 2 parts. One was a rear upright when I clipped a board while trimming my servo before a heat at slow speed (talk about embarassing). The second was the front crown gear stripped inside. I expect some more damage because I run mod but the car is holding up really well so far. Then again, I am a fairly decent driver and don't hit lots o' stuff. But when I do... IT'S BIG!!
As for hopups, I have a bit but I do not think they are all required for most racers.
Jurgen lightened center shaft
aluminum front shaft
aluminum rear shaft
countersunk upper deck (self)
alum oneway gear
B though E toe blocks
aluminum shims to change roll center
ti screw set
The biggest problem I see on this car is all of the front hinge pin slop. Even when new it was out of control. I understand there is a new pin set coming but we'll see. I have also heard of most people breaking drive cups for the main shaft as the #1 breakage though I am still on the original (knock on wood). I think part of the longevity of mine is the Jurgen shaft uses standard roll pins and there is zero slop or play. If anything they are a little tight but I like it. The drive train is still free since that is a fixed member so I don't think it hurts anything by having it tight.
Where are you in SoCal? I grew up and have family in SoCal so I may be bringing my Evo4 down to race over the holidays.
