Today i dropped my rear subframe to replace all my bushings and all 3 diff mounts prior to installing some stance al+ coilovers on my 87 tII. I was doing some research and saw that people have had additional welding done to their sub frame to strengthen it and i was curious what all should be done to properly strengthen it? i have access to an arc and mig welder and would like to do this prior to putting everything back together.
thank you
Andy

If you plan to compete in pro-am dont do it.

I just welded the inside of the diff mount part, mainly beacuse I run a solid front diff mount.

But never had a problem before or after doing this

as long as all your mounts are good you shouldn't have to weld anything on it... i've never welded anything on my subframes... btw, if you do, it won't be legal for pro-am or pro competition.. fyi

If you dont weld the front diff tab, then run a pin ion snubber. I have broken about 3.

I Didnt even think of the the rules when i did mine. So shitty. I have mine all stiched up and lightened.

Dirt-McGirt

More i think about it the more is pisses me off. lol. Mine feels so damn good. You can put a v8 in, you can weld knuckles and ****, but you cant stich up a subframe? ******* retards. Can you use expanding foam to stiffin the main part? What about locking out toe adjustment off the subframe to run Adj lateral links?

Looks like I'm not welding it then. Thanks for letting me know that. Off to the powder coaters.

hey jtp, heres a question thats been bugging me lately.
if i cant modify the subframe, then how the **** are people running rwd scions and ****? something is modified right there.
how are teams getting away with having a v8 powered 350z, but i cant modify my subframe to drop in a 13brew?

subframe can be modified to allow for clearance for oilpan, quick change etc... but can't be modified to strengthened.. i don't really get it.. and it's a touchy subject when it comes to what strengthens and what just allow for clearance... i don't agree with rwd scions at all, but money talks i guess... if anyone would like the 2011 Formula D rulebook to read the entire guidelines pm me your email and i'll send it over... it's too much to post up here..

Thats ******* stupid.

I'm doing it anyway. I dont care about going pro or pro am JUST because of the rules. THey dont make any sense at all. Most of them dont.....

Amen! I've read over the 2009 and 2010 FD rulebook and it's a streeeeeatch to allow a TC in. It's like a ugly second cousin to it's AWD platform.

J.T.P.

the good thing is that tanner's will be 4cyl next year, and the following year i've heard they'll be coming out with an actual rwd platform under the scion badging...

what team is it that got in trouble for using a supra rear subframe? wasnt it tanner foust?
it doesnt make sense, can you move the subframe?

Just installed solid bushings and pin ion snub. Ftw random welding just cause u can isnt the best idea.

8.4.1
Front cross member and/or front or rear sub-frame
Front and rear sub-frames and cross members must be stock and
available on the exact model that is competing in Formula Drift. The
subframe must also be mounted in the precise stock located, without
being moved in any plane. Front subframes may only be modified in the
interest of relocating or mounting of the steering rack. Rear subframes
may only be modified in the interest of mounting or relocating a
differential. The rear subframe must retain at least one major member
that spans the entire width of the subframe, thereby keeping the original
dimensions of the subframe intact. Any other modifications, cutting,
welding, strengthening, etc is not allowed.

well, i guess that answers my question.
im still saying they bend rules. i guess "he who controls the spice controls the universe".....or teams with enough money can bend the rules.
such bs

things are changing a lot though... the ones who use to enforce the rules are now gone, and sheriff Tony Angelo has stepped in. therefore a lot of the cars are no longer legal and new cars are being built to replace them... i.e. v8 scion, falken sky, falken 350z etc... unfortunately things can't happen all of a sudden, and the sport is still growing, so in time things will get sorted out..

This is what i like to hear.

thatnks for the rulebook btw jtp, youre the man!

justin, can you hit me with the rulebook. i heard it was supposed to be released sema time, but never got it from andy. would be cool to see the new rules for tech **** if i do the pro-am's this year. i was really only trying to attend XDC but still rules will be similar.
twinturbo92vr4@yahoo.com

thanks man.

there is also "appendix K" which isn't listed in standard issue/online rulebooks, however any team/driver can petition via appendix K to get inspected to pass tech.
so basically anything can be voided if you catch what im saying. idk if thats carrying into 2011, but dont see why it wouldnt. tony angelo is super good about checking cars, which is really good for the series. idk who techs during the UTI main tech day, but i would assume it'll be Tony, and with him being a fellow driver, i'm sure he wouldnt be pumped to see MISC BS going down.

as for the steering rack relocation i could've sworn in the 2010 FD rulebook, it said that was ILLEGAL! because i wanted to move mine higher up (towards the hood) to help alleviate my low ride height issues by having the tierods in less of a bind!
Fashion over form as always.

Thank God they're changing the rules and or enforcing them hardcore next year.

I have all the FD's saved that Versus aired and seeing some cars crash and reveil that it's really a freaking tube frame with a Sky or S13 panels on it makes me sad. I understand you want the best but it's so dumb to me to turn FD into NASCAR. i wanna see a chassis I can afford do amazing things not a over grown go-kart
