What are the differences between the 2 and 3 hole caster blocks... besides the addition of an outer hole no one seems to use?

Looks like Suburbs are the tire of choice there. Even the JConcepts sponsored guys were running them. Interesting!!!!!

control tyres, weren't they?

2 manufacturers for control tyres

correct. it was a control tire, i believe control foams too

What does that mean everyone uses the same tire? That's pretty cool!

Yep. Suburb 1.0s were the handout tire. I wish they'd bring that tire back

Yeah
One Hobbies was thinking about making a spec tire class.

It has it's pros/cons

I think it would be great if a hobby shop track would have a spec tire class ... I dont have the funds to have a bucket full of tires, if I new everyone in the class had the same tires I would be more inclined to run that style rc just for the spec tire reason.

It's a good idea to a point. IT helps keep the playing field fair. I like it but don't at the same time. I don't feel like going out to buy new tires cause a track says I have to compared to running a tire I know works with my driving style.

IIRC .030 higher axle location on the 2 hole vs. the 3 hole.

I'm not sure off hand why shimming the 3 hole all the way down wouldn't do the same thing...They may be using the 2 hole because you can get it in carbon??

Wild Cherry would know more, he's posted on it before but don't know what post # it would be.

Racers..by design don't like to be limited by tight spec rules. That's the way it would seem over the years anyway.

There's +'s and -'s to both open and spec tire rules.

If my local track picked either truck or buggy and added a spec tire class for it (with what ever motor limit they want) I would run that class over stock. I understand tires make a huge difference. And if the track ALWAYS used the same spec tire grab a couple pairs and your set for the year.

Not saying add a spec tire for every class there is just pick one and add it in.

What I dont like about spec is if its for a single race at an away track or a major race at your local track ... then your getting tires for one weekend you will never use again, but if the track has the spec class week in week out you will get your moneys worth out of the tires. It becomes about the drivers skill at that point which is what racing is all about.

Hm... interesting. Ill look into it some more... thanx for the info.

Can i get a Cherry to add his flava to this answer??

I got a b4.1 ft 3 months ago, been reading every post on here since then and ran it for the first time 2 weeks back. my track is very bumpy, medium traction but the track gets pretty dusty. running what seems to be popular setup options front- 30wt,#2, brown, rear-27.5, #2, green. Losi bk bar pink in back, losi taper pin front. most everything is mounted up (shock towers, camber links, etc) to match wild cherry setup he has mentioned to use multiple times. key thing is I am not on the +8mm chassis. lrp sphere esc with a novak ballistic 10.5 on board.

car is a handful. I am a decent driver (drive an sc10, run mostly in the amain of 36 drivers). buggy jumps awkward, pushes on slow and high speed steering, is loose as can be under power. Ive tuned down the power which has helped.

my main question. I just got losi bb and plan on converting. honestly I do not want to put much more $ into if I should just buy the worlds edition instead. the +8mm is around $50 and I can buy a worlds for $250. Im a low budget racer, need to spend my $ in the important areas. honest feedback, some setup tips to get this thing rolling or simply go buy a worlds and be done with it? appreciate the help, as I mentioned have been reading for about 3 months and you guys are great on the forum.

A spec tire is great in theory... but only if they control how many are sold too. The people willing to run a new set of spec tires every week will still force the majority to spend $ on tires to keep up.

Its the same thing with a blinky class. They did it to blackball boosted and level the playing field... but now the discussion is "whats the fastest motor and speedo combo" to run with a specific gear. So now people are buying multiple motors and speedos looking for the edge in speed... when all they had to do was run a boosted setup... or mod.

Its brushed stock class racing all over again. Battery motor and speedo wars...
