just added avid rack and hex set

the quality is awesome, these hex are the best looking and best quality, i have used pralines and hear some negative about jc.

the only play in my steering is just the servo. So sweet.

28 or 29/72 should be just fine with the 13.5.

I know many of the pros have used a 6.5 or even a 5.5 from time to time. I ran a 7.5 and it was a handful for me. If you can control the wheel spin, and find a set up that works with that much motor then maybe.

I have always ran mod in all my cars but recently went to a 13.5 in the B4.1. I am having much more fun with the 13.5. Geared right for your track you can pretty much keep up with anyone.

The only thing I miss is the speed on the straights. Nothing beats the thrill of a mod motor with the throttle pegged down the back straight.

It also depends on your track. If it is a large track with a long straight great. But if it is a small indoor track in someones garage then I would say go for the 13.5 or even a 17.5. Geared right they can be plenty fast.

Yes, it needs to be replaced...with a ball diff. The off the line stuttering is all electrical...sensor wire or speed control set up. In our gear diffs (when we ran them) we ran NOTHING heavier than 50wt shock oil as this was the very heaviest oil we put in them. Gear diffs are sooo unpredictable in the way they come out of the corners. Sometimes fine, other times they want to continue steering when you don't want them to.

I am running a Tekin RS with a Tekin 13.5 geared 69/31. At SRS in AZ it is the perfect combo for me. It is also the gearing combo used by several others at my track. I feel it is a good set up all around. Enough punch to clear the triple without too much run up, and fast enough on the straight to keep up with just about anyone. Even in the summer heat, I stay below 150 degrees on the motor and esc, with no ventilation in the body.

Ruonas car with some new bling by JC. Alu wing mounts anoyne?

Thank you, I was kinda thinking along those lines. I'll give it a shot tomorrow!!

For those running avid springs which ones are you using for the front and rear (I run at a small indoor clay track), also has anyone tried out the jconcept spur's??

yes, the jc spur is sweet, its true in round and a lot nicer, a.e's are not bad though.

With the shorty on med bight, I ran yellow fronts white rear and my car still oversteered like crazy, I threw in the full pack for tmrws racing, should be fine.

I am also running #3 pistons, the #2 even with 30 in rear, 32.5 up front was very soft with the avids....I have not drove it yet though..I will update you. I can just see myself going back to red losi 56 and throwing on yellow rears.

Thanks, I am actually going to be adding either rcshox dual stage pistons or MIP's setup..... I still need to build by b4.1, just waiting on some stuff to come in....

Tested out my b4.1 wc today and had problems with the turn buckle ball cups keep popping off the ball and one breaking on me. Has anyone else ran into this problem? What other good strong ball cups out there that'll work?

I always use rpm and haven't had one pop on me since (on my t4), and thats what I plan on using on my b4 wc..........

Someone today at the track was talking about some Lungsford ball cups. How are those?

are those bb shocks on j r car nice wing mounts

No big bores..it appears to actually be Losi springs...
