Good deal I rememer you telling everyone about it, But for some odd reason I couldn't remember the details. My buddy woody just did that with his brat. He put 235/75/15 (almost the same as a 30x9.50x15)it looks real good. Do you ever have power issues with the bigger tires like that, or slipping clutch. Are there any down falls to having the big tires?

Downfalls - well, that depends on a couple things. Mine are 215/75r15's - so 28's basically. This results in a 27.6% difference in speedo reading - so the speedo is WAY slow..... now mind you my speedo was calibrated for 175's at the factory because mine was a 2WD, so a car with a 185 speedo (an original 4WD car...) would not experience the same amount of difference.... still significant tho - over 20% for sure.

 

I got lucky, and by pure chance happened to install an 82 style D/R 4 speed - it has lower gearing for 3rd and 4th, and with the big tires is just about right - so my power is alright - especially because I'm running straight pipes, and a weber.

 

If you had an 83+ 4 speed, the power would be bad - 3rd and 4th (especially 4th) are just too high for tires that big - the RPM's are much to low for any power going down the freeway - expect to be in 3rd all the time....

 

A good amount of fender cutting and banging will be in order for large tires like that - but I'm sure you already know that....

 

If what you are working on is an 82 or older 4WD - absolutely you will have to upgrade to the larger 225mm clutch from the 83+ 4WD's - the 200mm clutch will slip badly with big tires.... you will also need the flywheel from the 83+ if you do this....

Actually - as much as he probably want's a weber - the number one thing he should do is get the gearing right - that means either an 81 or 82 D/R - or a 5 speed D/R from an EA82 (he still won't use 5th much - but at least there's 4th which is marginally lower, and 3rd for hills on the freeway...

 

It's seriously gutless with the 85 4 speed I bet.

 

Next up is a lift kit - if he hasn't done it already...

 

After that's done - time for a Weber - more low-end grunt that way. Just remove the muffler completely - it's not too loud, and sounds great.

 

Finish it off with a welded diff, or LSD if it's a street ride, and some custom bumpers etc - whatever he likes really.

 

On another note - I may be needing some Gen 1 Brat parts sometime soon. Did you see my post about the Gen 1 wagon I got? Possibly there could be some tradeing involved of parts from it for Gen 1 Brat stuff.....??!?

 

A lot of it's parts are going to the Brat I'm getting, but there's lots of wagon stuff left to be had. It's got a good little automatic tranny that I don't think I'll be needing - doors, glass, etc..... interested?

I guess he does have his rear end welded, and a big burley bumper on it. You might remember it, it was that dark gray one with the super swampers on it, we went up to reider pit in sultan.

He had the gray one and I had the red one we had just took off before you guys went wheelin'. Anyways I've got a few gen1 brat parts, just send me a wish list and I'll see what I can't get for you.

If I don't have it I'll ask around.
