The Roche ones look very good so far; great quality with no binding or slop.

I hear the Spec-R quickly develop slop so I stayed away from them.

The Xray ones are great quality and I used them last year, but I did snap an axle towards the end of the season in the same place that I've seen a few others snap, so decided to give Roche a try for this year.

We reckon the Tamiya DCJ's are some of the best in the business. Very smooth, super tough and you can use them when you use our T4HS Spool Cups - http://shop.smokem-racing.com/Smokem...DCJs_p_20.html. We also stock the Tamiya DCJ's and individual parts for maintenance.

You can try our T4V7 conversion for just a little bit more than that!

Will this fit reflex low deck, but I am sure not, since reflex V2 chassis front is backward

mac853, to answer your question, yes the belt will be loose. I have the eccentric all the way tight along w/ a belt tensioner (might be over kill, but..) and it works fine.

I ran the RSD V2 yesterday and it was fast. I ran the top deck w/ the 2 rear layshaft screws in and I had a tad too much turn in mid corner. nothing that wasn't drivable, just wasn't to my liking. I am going to try the top deck post to the motor mount next time and have all the 4 screws to the layshaft off to see if they will cure that, hopefully that will give my car a tad more push mid corner, or round out the corner.

As Christian states it does carry a ton more corner speed. very nice chassis.

Very good alternative to the Xray stock upper deck. I've ordered tons of stuff over the year from rcmarket. Very good company and shipping doesn't take that long at all. Usually about a week to get here to Texas.
That looked great 'til I saw the cost for shipping was as much as the price of the top plate. I suspect it would be well worthwhile if I were buying more items, but this is really all I need.

Thanks, Mike! I'm not really familiar with the Spec-R stuff. Do you happen to have a link or anything I could check out? Which Spec-R model components would fit the T4?

That's very intriguing! But what if I want to run the top plate with full stiffness (I also run on carpet, not just asphalt)? I see holes on the plate for two more screws, but there is a gap between the top plate and the center pulley mount. Do you provide shims to take up the space?

Thanks!
Tommy

There's this one:
http://www.reflexracing.net/SPR027-U...mm_p_1778.html

Which is just a budget top deck replacement.

And this one:
http://www.reflexracing.net/SPR027-U...T4_p_1794.html

Which is a top-deck and post. I ran the top deck with post on my T4, and I thought it made the flex better on carpet. Better rear stability, but more steering and response. That's with the layshaft bulkhead screws removed.

Fitment wasn't perfect, though. It seemed to be a touch longer than the kit one, so I did some file work on it. Worked on track, though. Also, the aluminum is a bit soft. Make sure you use the longest screws you can get to fit in there on the bottom.

Depends on motor and esc but I'd start at 6.2 if I did not know any better. At large track I have been running 6.0 lately, that's with Hobbywing motor.
However for titc we ran 5.4 but that was a special motor compared to others. So can be very different.
