im pretty sure that strange housing in your car was designed by dave at team Z

I use UPR too, my whole front end is from them

You cant compare the guys suspension that are running sub 1.2 short times and 6 second passes with a 9 or 10 second car. The relocated uppers are designed to work on non mini tubbed cars to get the suspension geometry closer to where it needs to be because you cannot get the rear end low enough without mini tubbing the car. I kick myself for not buying them

There are alot of varibles here though, you cant say, just go and use brand A or B and bolt on parts and expect things to work magically.

I'm not doubting you about the Strange housing, but this is the second one I've ordered from J.C., I've talked to him a million times, and he never mentioned Dave Zimmerman designing the housing. If it's true, I'd be mad if I was Dave. (I should ask him about it)

Also, I agree about not just issuing a blanket statement and expecting magic but I should mention my personal experience with a 9 or 10 second car.

Back in 2003, I ordered UPR Pro Series suspension for my 306/ATI P1SC/T-5/8.8/26x10 notchback. I laid the UPR arms next to the factory arms to approximate the proper length and I installed them that way without checking the pinion angle because I didn't have the proper tools to check it. I took the car to the track completely untested (first time with the entire combo) The car went 10.17 @ 132 with a 1.39 60' time on 26" tires. No relocation kit needed on that car.

I can't even see how Team Z and UPR is a fair comparison. If I am buying suspension, Team Z is a no brainer. If I'm buying billet pedals and shift knobs, UPR is my company of choice. Just my opinion so feel free to flush it like the stinky turd that it is.

I suppose he wouldn't sell them if they break though?

Do a search on UPR on here and the corral.

Okay, time to talk about reality.
In reality, just about ALL of those types of companies have designs done by a machinist, or someone that has experience in manufacturing.

In reality, no one at those companies likely even has a clue what Finite Element Analysis is, or means. So, IMHO, most of those designs are "good luck SUCKER designs".


Again, in reality, from a profit point of view, it makes zero sense to have a top notch experienced Principal structural Mechanical Engineer on staff for over $100K/year and have a few hundred thousand of dollars in software. Heck how do you think things were done in the 50's -70's? Many of those designs were based on experience.


Note: There are a few companies that do have the income and sales (and respect) to have real structural mechanical engineers. But, those companies are the exception verses the rule.


*I* care about handling. That's why I use MM (Maximum Motorsports) stuff. MM has a very knowledgeable and experienced structural mechanical engineer that has the software and tools to do real design and analysis. WOW, what a concept!


So, please be VERY careful about ANY aftermarket component you put on your car! Some are down right MORONIC in their design. And, the company/execs are so *****ing *******, they won't even do cheap/simple/no-cost things to fix an otherwise VERY risky ****ed design.


Hey, you asked!
