Sorry, I might be over thinking this... are you saying that you have 4 to 5 mm of clips to limit up travel? In my front I have 2 of the thick one's and rear has 1 thick one and 1 thin one. Sorry if I over-thunk this.

Speaking of cactus, I plan on taking a week or so of leave to go and race at cactus. I'm just gonna run JC chassis sheet's. I'm from Tucson originally and used to go every year since 2000. Haven't been to the cactus since I joined the Army. Seeing that I'm so close, I cant really miss it.

I guess we should add whether or not we are using the dust covers I know they will limit travel by a few mm themselves. Has anyone measured the amount of up travel the dust covers take up so those that do not use them can compensate?

I ran the MTK basket and pinned loved it for my driving style and track. I also had my front clicker locked down full 4x4. Front diff filled with 20k & rear with 7k. Truck could driven more agressively with no fear of excessive slipping. I think you'll see a huge difference. Now I run rcshox center diff and it's a whole new world. But if it weren't for that I would have stayed basket and pinned.

Thanks for the quick reply Guys...

Actually, I too was under the impression that the Pinned Shaft would work with the MTK Clutch Basket? At least that is what I remember people on here running a few month back... Could MTK also chime in on this?

A few things I forgot to ask... seems like from the last few pages I have read... people have gone down with their diff oil in the front... 30K was the Front Diff Oil set-up from what I remember? Is this still used for big outdoor tracks and the low Diff Oils are for carpet racing? Thanks for the 20K tip jamr1130! Also, are either of the Underdrive or Overdrive pulleys recommended with the Pinned Shaft & Clutch Basket combo? Any suggestions on tension?

Sorry for all the questions... doing an extensive rebuild and want to get as much right as possible before finally hitting the track after a long hiatus.

Thanks once again for any assistance anyone can share!

You got it. With this amount of of up-travel limit, the chassis still can bottom out. Oh, and no shock boots.

Hi Guys
I have a strange problem and as I am racing on tarmac/aphalt as my clubs offroad race track is being worked on for the summer season it does not seem easy to find information!

My truck does suffer with a loose rear but it gets better after 1-2 minutes of racing (probably as the tyres have more temperature), when I get around 6 minutes into a race the rear end will get very loose on sweepers and 360 or flip on tight corners

If you could try and offer some advice I would really appreciate it as leading and winning all 5 minute qualifers is great but a 7 minute final gets fustrating when after 6 minutes your can will spin out 2-3 times per lap

Here is my current setup that is all geared towards getting rear traction but may be causing some of the problem

Camber Front 0, Rear 2
Toe Front 0, Rear 3+2 Block
Shocks Front Yellow/35, Rear Blue/30, No rebound No limiting
Diff Fluid 30K/7K
Slipper MTK Basket 3 x HD pads, nut flush
Clicker Locked
Tyres Front Enduro, Rear Caliber
Ride Height Front 20, Rear 15
Swaybars 2mm Front & Rear
ESC/Motor Castle MMP, 3800

My thoughts after today were to limit shock travel in both directions, stiffen rear springs, tighten the slipper more or get the finals shortened to 5 minutes

Keep up the good work and thanks again

pinned or non-pinned with the clutch basket?

Strange i have the small black rubber washers on my shockshafts..and i do not use anytgi. Else and i have maximum out and up travel, and cant see any mark on my rear arms...

I have my truck apart right now waiting on a new idler gear...so great time to change out the diff fluids. All I have available is 5k, 7k, and 30k. I will be adding the MTK basket upon rebuilding for this Tuesday night's race. I have been running 30k front, 7k rear and have had a persistent understeer that keeps me from diving into the turns. I have been approaching the problem with springs, bars, and shims under the ballstuds. Its getting better for sure. So here is my question:
-Using my available diff fluids, what should I mix to get more of a 15-20k front? I was just going to go 50/50 with the 30k and the 5k and see what happens.
This is an indoor clay tight track (PRCR).Thanks!

Try just 7K front and 5k rear and see how that is.

I race on an Asphalt track and I can tell you that if you run less than 10,000 rear diff fluid the truck gets loose. I can also recommend the HPI BLITZ stock tires on asphalt I am getting 100 runs on mine and my truck is one of the fastest there. You also don't mention your camber link locations, these are important as a long flat camber link will give you more traction.

Sweet, thanks. I don't run the boots either.

I am not running pinned because I race on a smooth clay track. You dont want to run pinned with the basket you either run pinned or just the basket.
