325's without relocating leafs? No Prob

UPC = Upper control arm? I would think a shorter ball joint will mess w you WINNING geometry, right?

LOL, woops, thanks Ron. Winning geometry? You never really know until you try.

Yup, stock disk brake spindles out of a Chevelle. No Guldstrand mod.

More questions: I have been looking for the best taller spindle. (Almost all of the aftermarket taller spindle have a 2" drop built in.) How much taller is the Chevelle spindle than a stock Camaro spindle? What model Chevelle? Did you use the Camaro steering arm?

Running the taller spindle will challenge your rubbing issue. ATS and other after market spindles are supposed to help geometry. I have never seen one but my guess is that the lower mounting point to the steering arm is a little lower than stock which would help level out your tie rod arm and in turn help with bump steer. The extra length of the spindle up top will help with camber gain by raising the UCA mounting point.

With the Global West control arms I dont have issues with camber gain. As far as bump steer goes I dont feel it although I am running a Steeroids rack and pinion which may be helping.

I'm pretty sure the Chevelle and Camaro spindles are the same. I picked up the spindle/disk brake set up many many years ago from a guy that was parting out his Chevelle. I tried it on my Camaro and it worked. I cant remember what year Chevelle for sure and wish I could remember but I think it was a 1970. Oh, and yes I am using the Camaro stock steering arm.

My basic philosify is if it aint broke dont fix it. This hobby is expensive enough as it is. I dont follow what everybody else is doing, I pretty much just do my own little test and tune on the road course and put together what works for me. There are a handful of guys that can attest that the front of my car sticks like glue but the rear has always been a bit loose and I have a bit of tire spin pulling out of the corners which is why I decided on the mini tub and 315's. I may have been able to get away with a larger front sway bar but with the amount of torque I'm putting down I think the rear tires needed to happen.

Hay Gaetano,

What rear leafs are you using? Also your wheels are the OEM's or aftermarket? I'm starting back on my car and looking to just build it to have some fun and NOT cost lost of cash. Also woundering why you did not want to do full mini tub and not move leafs in board?

I went through three sets of leaf springs and manufacturers before sticking with the Global West. When I ordered them from Global West back in 2002 they were offered in a 2" drop and I asked them to de-arch them another 1". I have heard they offer them in a 3" drop now. I never have taken the time to check the rating on them and that is one thing I dont like about a few of the leaf spring manufacturers. They dont tell you their lb/inch rating.

The wheels I picked up are OEM. Aside from the aftermarket wheels weighing 3 lbs heavier, I was at Infineon earlier this season when a fourth gen Camaro broke an aftermarket vette style wheel coming out of turn 7 due to bad forging at the hub. The car was totaled. That right there told me that OEM is the only way to go.

I didn't due a full mini tub because I did not want to move my leaf springs and shocks in board. Our cars have alot of roll to them and thats fine for autocross but on the road course you want the car as flat as possible in the corners. Relocating the springs in board narrows the pivot point which leaves more weight hanging over each side of the leaf spring. Same goes for the shocks. I wanted to keep them outside of the frame rails for more stability.

BEAUTIFUL SETUP!

Thanks, I appreciate the support. I made it out to a NASA event at Thunderhill a few weeks ago only to fail tech. Things look to be getting a little strict due to a few serious mishaps on the track. I had been running the same seat for years and now I have been asked to either run an FIA approved seat or a seat back brace.

I was supposed to hit Infineon June 11th and twelve but my Moser axels didn't get to me in time and I had already pulled the other axles.

What ticks me off is now that the tech guy has put that out there, even if I decided to run with another club with the seat configured as it is, what he said will always weigh in the back of my head so I need to make a decision on what to do.

Cant blame the tech guy, safety first. I think my only track day this season will be Buttonwillow July 30th and then I'll start working a little harder towards safety. FIA approved seat, window net, and fire suppression system.
