You're probably right. I'm going by what someone told me to do. You've got a lot of experience over me. Hey are those your sponsors listed below and how difficult is it to get sponsored. I want to go all out and do my best to be sponsored.

im interested why is it that all of you are so obsessed with spools? wouldnt a front one-way be a much better alternative to both a spool and diff? is it that you run on carpet. if this is the case i understand. but for asphalt why would you want a spool? wouldnt this create massive load on the drivetrain and tyres/chassis mid corner? it would also upset the cars corner exit balance and create corner entry off power understeer and then on power exit oversteer (and possibly if your setup was really bad it would snap the rear out). this sounds like the worst possible situation, whereas with a oneway you would still get the same effect but you would also get the off power effect of a differential which would make driving corners much easier as yu would have oversteer coming in like a diff and then full lock on the exit for max power down. and if one comes in the kit why the hell would you buy either a diff or a spool. if you own a 415 you should have a speed control that it deserves and this would surely have auto brake functions on it that would allow engine brake to slow you down enough to carry the speed through the corner without the need for a diff or spool for braking.

The upcoming Reedy race requires 4 wheel braking, thus either a spool or diff up front and the locked center pully is required. Spool gives you more on power steering.

LOL spoll in the rear should make it drive like a 1/8 pan car and give you plenty of steering on power.

Spools were used at almost every round of the BRCA nationals by the top drivers in mod. You can overcome the off power push by using a more agressive setup on front (softer springs are a necessary evil on front here). A spool will allow more agressive driving, which makes for faster laptimes, whilst making the car more secure for close racing.

hi guys

im after a 415 std kit but it seems like they are all out of stock in hk and japan sites.

because the 415ms is out does that mean they wont make anymore 415 std kits? i know the ms kit is much better but just on abit of a budget.

cheers for all comments

Just out of interest have you ever actually tried a spool?

It's a very useful tuning aid, just gives the car more options.

I'm sorry but i totally disagree with what your saying about the speed control... In stock racing the fastest way is actually to have a little positive throttle (ie on throttle at neutral), and the amount brakes are used it is not worth setting up drag-brakes.

Also the biggest positive of the spool is that it gives 4wd drive braking, as previuosly mentioned, which is a BIG bonus in finals with close fields...believe me.

I personally was very negative about spools when ifirst got the car, i just couldn't see the point with them, they just didn't have the turn-in that i required, however I have stuck with it (and helped by the great tuneability of the 415) I am now pretty convinced it is the fastest way over 5mins... if not the fastest for out-right lap times.

I'm in agreement with TRF415boy here, if your having trouble with the turn-in of the spool try these things.
1) softer srpings on the front (with the 1 way I run White/Blue F/R, with the spool I use Blue/Blue)
2) Move the shocks in one hole on the front shock tower (1-way, i use postion 4, spool I use position 3)
3) try using less anti-dive on the front (remove any shims from underneath the front suspension blocks). You can even try a bit of pro dive, by placing shims underneath the front bridge block. This also reduces the castor angle.
4) Try running inboard toe-out on the front, ie running the C/A or D/A combination of front blocks (you'll need the front A-bridge for this).

Hope it helps
Ed

I have 1 of Randys spools on the way ..I never owned a car with a diff up front I'm pritty fast now at my local track 1st or 2nd every week I cant wait to see how the spool works it will be a true test and the lap times will tell...you can check out our track at WWW.ALLENSRCCARS.COM....

To get arround bying an A Bridge you can use the rear A bridge flipped up dide down on the front on 3mm of shims
