39's on Comp. F-toy?

[FYRDUDE]

Anyone running 39" rubber in comps? Thinking about stepping up to bigger meat with everything being chromo now. Would never have tried it with my 4-runner. But with lighter weight of the F-toy it seems like it might be possible. That's still a whole lot of leverage against the toy drivetrain, especially when your hammering. Let's hear your thoughts. I thought someone out there was running 39's? Anyone?

Hobie's got 38" TSL's

I thought someone had 40's but not sure.

Get Bobbies output and 30 Spliners and hammer down

The only thing I'm missing is the output shaft. I think it might actually be able to handle a little flogging.

I think it may have been Chopperman?

Ghettowheeler has 39" Iroks on his F-Toy, but hasn't competed with them. He had to alter the chassis to fit them. Camo had 39's for a short time, but never competed in them either, I believe.

Seams everyone competing runs 36-38" but I am considering running exhibition with my 42's

You should be able to run 39's with minimal breakage, just fitting them will be a problem. Sean's 38" SX's rub a little, so I bet you'd need a tall rig or wide axles to fit them.

Todd C. ran 39's at the Donnor comp.

Did Todd C. have to alter his chassis to fit the 39's? Maybe just running some bump stops in the back would solve that issue.

I am currently running 39.5 Iroks on the 4runner and plan to use those on the F-toy. I hammer the runner pretty hard http://www.orvpark.com/multimedia/dozer-hill.asp ...this was with the 38 sx's but I don't drive any different with the Iroks. I broke 1 short inner birf elim and that was my fault. I'll be using Bobby's 30 spliners and an auto trans so maybe they'll hold up ok. We'll see.

I'll take a couple pics and start my build up thread later this week.

The outer-lower bar really limits tire choices unless you mount the chassis way up high, limit your suspension travel, or strech the wheel base way out.

We would like to put on 39's on Matt's FT but the frame limits us to the 37's we have on now. They allready get way into the lower bars.

[ghettowheeler]

i had to modify the rear lower fender bars to fit the 39.5 iroks.

Are these mods ok for a comp rig?

[CronusTRD]

no

[FYRDUDE]

Ghettowheeler,
What springs are you using? My chassis sits 2" above the frame rail and I have 4" lift springs. I wonder if I installed some bump stops I would avoid hitting the rear bars. But then it would severly limit upward travel. Also, what WB are you running? I was doing some measurements and it looks like the tires will hit at the front of the tire unless I stretch my WB a little. I think I'm sitting close to 107" Maybe less. Also, what backspacing are you running? I almost rub with my 37's and 1.5" wheel spacers. Thanks for the help.

the marlincrawler ftoy had some 40" iroks at the tinbender jambo but it looked like they rubbed bad in the rear of the front tire

[FYRDUDE]

After doing a few measurements, I think I would have to move the rear back quite a bit.

I have had 39.5 X 13.5 X 17 IROKS on my buggy since the very beginning. Never looked back. I have to run front wheel spacers to be able to turn at all! And I built the chassis up high from the start for headroom.

Well, I was going to add a picture, but lazy Lance hasn't given my star back. I sent him the money almost 2 months ago, and they cashed the check, but still no star.

If someone else wants to post 'em for me, send me an e-mail: ltcdds@pacbell.net

Todd C,
What height is your chassis above your frame? Also, what's your WB? We should hit Hollister some time. Didn't know there was another F-toy in the area.

I'm going in the morning (Sunday)! Come AWN.

I'll have to take some measurements for you.

I'm not just in the area, I'm only about four miles towards town from Hollister Hills! Just off Cienega Road.

Here's Todd C's rig on 39's

[mtbrjon]

2 more of Todd's rig. Are your rear springs in board? Looks like you might not have the flex that i'm anticipating but a little hard to tell from these pics and your chassis looks a little high on the frame compared to others i've seen.

Oh, heck no!

Rear springs are AllPro from about 4 years ago. I removed the shortest leaf in order to get a little more flex. I don't feel as though I've been limited too much by not inboarding them.

My rig has been so fun and so dependable that most of the time I have just used and enjoyed it. Don't forget, my Formula Toy has been running and pretty much in the same form for over 2 years. Even though Lisa's and Re:Todd's have been done a little longer, they have taken them back apart and rebuilt and changed them a lot more than I have.

Have to work Sunday, but we definately need to wheel sometime soon.

in the front i am running Trail gears 4" springs with the 2 bottom leafs removed with bump stops.in the rear they are some Ford F150 or Ford explorer stock pickn pull specials with no bump stops.with the 37's i was running allpro 4" rears but with the 4D's i had to find a spring with the center pin way offset.from the allpro's to the ford springs it moved my wheel base from 105.5" to 111.5" in order to clear the rear bar.i don't plan on competing any more so i re positioned the rear fender bar.that was the only thing about the ftoy chassis i don't like.i am running 1.5" spacers all the way around with 2.5" back spaced wheels.works great with no more rubbage.
