Hi Guys,

Fixed Spool or One way

If given a choice which would you go with?
Track would be outdoor aspahalt

It would help me decide which to use
Thanks for any input !

I like a one-way for any track, you can make your driving style adapt to the one-way.

One way for sure on Aspahlt if your track allows them

There is no one fits all choice.......every time my local asphalt tracks change their layout, what im faster with changes as well.......with the layoput right now, Im faster with a spool.......try them all....and let your laptimes decide for you

We have seen that one ways can generate fast single laps but over 5 minutes spools are faster.

With the one way the point where you let off the throttle and turn in are critical. It is easy to overshoot corners and if you are getting pressure during a race you may blow a corner and lose a position with a one way.

With a spool you can carry throttle deeper into corners and pass one way equipped cars every time. Spools are better for heads up racing in traffic because they allow adjust you lines more in corners and still get the car through. With a one way you can only early or late apex a corner. If you adjust mid corner you will push off line or spin out. With a spool you can do whatever you want. All you have to do is steer the car where you want to be and squeeze the throttle.

On hot days one ways will overheat the tires where spools keep the tires cooler longer.

We have found on our car the spool is the way to go 95% of the time on asphalt. One ways are the way to got 95% of the time on rubber/carpet. Diffs are the way to go 99% of the time on foam/carpet.

FYI, US team driver are all pretty much good friends with each other. We all talk about our cars and I can say all of the above will work on a TC3 (According to Barry), XXXS (Todd Hodge), Tam 415 (Dave Jun), Yok CGM (Chris Tosolini), Xray (Jared Scott)

Thanks Joe....between a new baby, wife's masters degree and work I haven't raced much in the last 2 years! I have been to every major race in the US over the last 3 years....but I was working not racing!

Thanks everyone for their valuable input!

AdrianM- Thanks it was very convincing!

Would I be safe to assume that the Pros would most of the time use a spool when given a choice?

I run a belt car too, should I run a Centre Oneway to complement? or should I jus run it normal ?


Anyone would like to differ??

Thanks again!!

I agree with what Joe said. It's a personal preference thing. As for me, I never run anything but 2 diffs in all my cars. If the car has a center one way I lock it down.

I've tried one ways and spools but I keep going back to diffs as no matter what I do I cannot improve my lap times with either, and I feel more comfortable with the front diff anyways.

I'm kinda like cartman34 as I like diffs in the car and the only other way for me is the spool but then I sometimes knock a tooth or two out of my bevel gear if I hit something too hard. I just run a really tight front diff most of the time.

Diffs are OK at club races if you want to keep things casual. However, you don't get the pull out of a corner with a diff that you get with the one way or spool. You do need different setups with with a spool or one way than with a diff. All it take is one serious guy that can set up a car good to make it so you have to run a spool or one way.

According to Barry Baker his standard TC3 setup is for a spool or one way. He says he doesn't even bring a front diff to a race unless its foam on carpet because at a high level racing they just don't work.

There is no doubt that spools are rough on parts. If you crash a lot spools are not for you. Shaft cars especially have a rough time. If you touch anything with a front wheel you will blow a bevel gear. This is why Hara had so many DNF's at the 2002 and 2003 Reedy races.

Belt car are not immune but you can have a few hit before things go wrong. Belt cars will break spool outputs and caster blocks.

i kind of think of it this way now, proebly wrong.

one-way= when lots of steering is needed
spool= when high traction, i think this gives understeer and a hard driving style is needed
diff= when low grip

AdrianM I also agree with you 100% on your assessment. I have run spools alot in the past and do like them but most of the time I keep up well with the diff. Sometimes I do need to run the spool though to keep up in certain condidtions and depending on who is racing that day.

As for gears I will be stocking up on bevel gears!!!!!
