Time for wheelies!

Well after three months of nothing but headaches from the rearend shop I finally got my 9" and it in and installed ready for Sevenstock. I still need to weld the brackets for the brake lines but zip ties will hold me to get by for Sevenstock.
Right now I am using the factory 4 links, but am in the process of making cromoly adjustable 4 link replacements that way I can make some slight adjustments/pinion. I am running 26x8.5x16 ET's and it was a very tight fit. I had to trim the front lower fender a little. I don't know how those Aussies fit a 9" tire under stock chassis. They must hammer the shit out of the body and fenders!
Well, here are some pics.

Looks good Jay... Did your lazer cut brackets line up perfect?? or did you have to redrill some of the holes?? I want a set of those brackets

Some run stock frame rails with new wheel tubs... not sure if they notch the outter side of the frame rail for extra sidewall clearance

Well, the dumbasses at the rearend shop did not square up the brakets when they welded them up so yes I had to enlargen a couple of holes. Also with the larger diameter housing tube they diden't raise the holes for the shock mount so the bottom of the shock would hit the housing tube so you wouldn't be able to put the bolt thru. SO I had to grind the bottom of the shock/strut to clear enough to be able to put the bolt thru. They did a pretty shotty job all in all, but the lazer brakets came out great, just need a compitant rearend guy who knows what he is doing to weld them up.

Whats the width of the rear from brake rotor to brake rotor??

Also, whats your back spacing on the wheels?

I am pretty sure it was 51.25" for disc to disc and that was with a 4.5 backspace wheel. It is very tight with the 26x 8.5 slicks. I'm going to have to do some more massaging. Also with the ford explorer disc brakes the left rear caliper lower bolt is right below the center tie bar bracket in the frame and if I jounce the suspension it hits so I have to notch that out. All in all I think its going to work out ok. We'll see.

Jesuscookies 10-03-08 02:55 PM

I have 8.5's in the back and they fit snugly, but well. You can get a 9 to fit on the passenger side with no mods, but not the driver side. The Gas tank, and panhard bar mount is in the way. If you remove the tank, and mounting bracket for the panhard, Along with knocking the shit out of the inner body well, 9's will fit.

Yep, I'll probably ditch the stock fuel tank and mount a fuel cell in the trunk in the near future anyway.

Finally got my adjustable chromoly 4 links and panhard today with hine joints to replace the factory one's and installed them today. It's a breeze to make adjustments now! Finally ready to make some runs with the new rearend.:)
Here's some pics. from today.

Finally ran the car tonight in the 1/8 mile for the first time with the new rearend. I wasn't used to tires actually hooking up and on my first run I was thrown back in the seat and let off on the gas pedal and ran a 9.5 but the car went straight as an arrow. After getting used to the new rearend my last run netted an 8.2 at 84 mph with a 1.7 60ft. I know it aint' no 9 second car that you guys are used to but I am proud of it for a 12a with a weber 48 all motor. On that last run I smoked a heavy modified Mach1 mustang- he was pissed.:lol: I know I can get down into the 7's with a higher launch rpm and some tweaks here and there. I am very happy with how everything turned out and look forward to better my times. :) Heres' a picture of my time slip. I'm in the right- toyota lane. I need to get some skinnies up front as my car was pretty loose at the top end.

Hook up with manny he knows his shit about suspension setups bro

Whiteboy at MPH Racecars in new haven CT has Toyota and Mazda bolt on adjustable bars right on the shelf..... They work real well.
Give him a call

ultimatejay 11-07-08 08:33 PM

^ Thanks guys. The 9 second set up is not in my budget yet and with the looks of this economy it aint' going to be there anytime soon.

I was the only rotary at the racetrack last night and it was fun blowing by some v8's on the track and people looking at my engine and saying, " What is that?" LOL. Next time out, I'm going to side step at 9000rpm's and see what happens. Hopefully the TII trans will hold up. hehe.

rex3- I had my links made at a local machine/race shop by my area. My dad knows the guy. If you want the shops phone number just shoot me a pm. Those Links put a big hole in my pocket though.

myfc3s 11-08-08 04:22 PM

Where do you go to run this bad boy?

prrex4ever 11-08-08 04:33 PM

Awesome! Looks great and seems to run just as good. Congrats.

a_reyes1014 11-08-08 07:05 PM

hey jay congrats on the setup. lookin good. i have a similar setup nine inch on a first gen rx7 without cutting anything. right now it fits a 26x10.5x15 tire under it with a little more room. im having a problem with setting it up. the car kicks out a little to the right under light acceleration and especially with some boost on it. this is my first time doing suspension tuning and not sure what to look for. i have after market links with adjustable rod ends to help with the tuning. if i try to get my pinion angle correct it kicks out to the right. if i try to correct the kicking out i get bad pinion angle. if you guys know how to do this please help. i know this car has a lot more in it i just have to get all the little things worked out before i push more boost. i was told to setup the links with no preload on any of the links by the guys at grannys who sold me the setup. i tried but i feel like there is more to it than that.

I am by no means a chassis set up expert. I set my links the same length as the stock one's and set my pinion angle just a tad down. My car launches straight though, so I'm not messing with anything right now. The first thing I would check is make sure your rearend is perfectly parallel to the front axle. In other words the rear toe is straight and not off to one side, in your case to the right. If that checks out then I would check your panhard rod and adjustment. My friend has the same car as you and had the same problem that you had and he ended up making a custom panhard rod set up and it fixed his problem.

myfc3s- I ran my car at Irwindale dragway. Every thursday night they have run what you brung night. I should be back there in a couple of weeks. Going to do some tweaks and hopefully get down into the 7's.

a_reyes1014 11-08-08 11:35 PM

thanks for the info jay and hope it gets better each time you get out there. im running the stock watts link so i cant really adjust it but will check for the toe. also my angle is set to -5 is that ok? where is yours set?

myfc3s 11-08-08 11:54 PM

cool

The car looks great Jay, you really did a good job and you should be proud of yourself!
