Spool is what some racers refer to as a locked front differential. Basically, what they are doing is replacing the front differential with a different piece or modifying the existing one so that it will lock it.

My Shoo Goo is holding up, LOCKED DIFF. I ran it in the parking lot, nice set up. I run on slightly bumpy surface, no too much traction, unless we put down some VHT, and fairly long str8.

Here's my set up for Stock Sedan Racing:
Front:
Rear Shock Tower, upper middle shock hole
Oil 30W
1.5 Camber
Ride Height 6mm
Silver Springs

Rear
Rear shock tower, Upper outer shock hole
Oil 25W
1.5 Camber
Ride Height 5.5
Green Springs

6.34 FGR

Seems good but I'll know for sure Sunday when I put it on the track.

Hi guys. Greetings from Malta.

TONY. I have checked it all again. With rear tower up front, standard shocks without rebound stops, and no spacers anywhere, and with the old single hole bottom arms, if I push the car down I can get the chassis to bottom out before the shocks do. This is with the shocks mounted on the innermost hole at the top. Perhaps that's what makes the difference. It's to get the front shocks angled as close to the rear ones.

Incidentally, we have always found the TC3 handles best with the same oil and springs front and rear, and a fairly soft set up. at least on out track anyway.

We went down again yesterday to play with tyres but the track was so filthy after the rain that lap times were about 2 seconds slower. Just to give you an idea. Tuesday i was running early 18s with a best lap in 17.9 with my MR4. Yesterday I couldn't get below 20. Son Josh with the TC3 couldn't get below 18.5 when he's been in the 16s with a good track.

That's the problem, living so close to the Sahara. When it rains and the wind blows from the South it brings half the desert sand with it..............and seems to deposit most of it on our track!

Regards

Joe from sunny Malta.

Hi Mandy. Greetings from Malta.

What I call the rebound stops are the white washers you insert in the shocks, to stop them extending fully.

I suspect the newer TC3s don't have them as they now have droop screws that see to that.

We like to run our cars with plenty of droop.

Hi Guys,

We just received more Titanium racing parts for the TC3 (screw kits, ball ends set, and input shafts...all in Titanium) Check them out on our website

Thanks

johnbull. I think we are talking about 2 different things. I'm talking about ride height....that's the height the car sits at when fully race ready. With the rear tower on the front and the one-hole front arms, you should not be able to LOWER the front of the car below 5mm. That's the drawback of the one-hole front arms.

Now, there are numerous ways around this, but the easiest is to just get the new front arms....unless you LIKE the car at 5mm, which you might on some outdoor tracks.

No matter what ride height you are at, you should be able to push the car down and have it touch before the shocks bottom out. Hopefully

Hi Tony,

So what you are saying is that the standard springs are too long, and therefore that's why it won't sit at 5mm or below.

Well funnily enough I actually run a longer spring, but because it is a fair bit softer it compresses and reduces it's length by about 1/4 when the car is fitted with cells and is on it's wheels.

Perhaps this spring, with the car on it's wheels, and compressed with the car's weight, does work out a bit shorter than standard.

I can't think of any other reason, but thinking about it, if a shorter spring does the trick, then that too is an easy way around the problem.

On a different tack, I received my copy of the On road Worlds video yesterday. I definately recommend it.

Didn't Barry Baker just throw it away! All he needed to do was stay in second.

regards

Joe from sunny Malta.

Hy guys i will be experimenting with a spool this week on carpet with rubber tires. IM gonna throw it in and run and expect an on power push, no biggy. Ill drop a spring rate, maybe add camber.
I know this will give me the pull im looking for. Hope it works.

O ya since i saw people with their foam carpet setups here is mine,

FRONT-diff loose
white springs
80 wt oil
camber-2 degrees
down and in camber link
6 degrees total caster. no toe in or out, neutral
shock holes, outside holes.
normal arms with 1 hole lower
ride height 5mm

REAR-diff loose
purple springs
70 wt oil
camber -1.5 degrees
up and in camber link
outside hole on hub carrier
no caster(duh)
3.5 degrees anti squat
shock holes,in all the way
0 degrees toe in
shortened wheelbase with custom machined arms. makes car 253 mm.
ride height is 5mm

Those springs and that oil looks really stiff! Does that usually work?

I use the stock 72 (48p) and sometimes drop to a 70 (48p).

Yes it does work Boomer. There is so much traction that it has to be stiff to keep the car from rolling over. I'm not saying u can go somewhat softer but this is what i have been working with.

TRL for 64 pitch i usually use a 100, 96 is also a good size, as well as 104 if you run mod motors.

Trinityracenut If you are gonna be at Trackside (your handle says Wisconsin) there is a setup for that track on TonyP's website. Even if you are going to another carpet track it's worth looking at.
