Maybe a 2015 Z28, as decontented as they will allow you to order one, but not a current Z06.

The 'hot ticket' in new cars for open tracking is going to be the new, much lighter, 6th gen Z28 if and when it is ever released.

The motor had 74k miles on it. Impressive for what it has been through. We ordered a balanced rotating assembly from Texas Speed and also have a set of AFR 215 Mongoose heads in the mail. Conklin Racing Engines will do all the fitment and file the rings, we will do the final assembly at UMI.

It looks almost like they're advertising, doesn't it?? Weird that the direct manufacturer of the suspension parts installed all the parts they manufacture onto a car with their logo plastered all over it to take to races and attract business!

Well isn't that the point of Hot Rodding and modding cars as a personal hobby? Add the fact that UMI is a company we are thankful for making products for these "16 yr old" vehicles" so we can enjoy to keep them running and racing them. PLUS they go to events to promote/advertise their product and SHOW that it works.

No one would dump money into a car for mods if they just kept saving and just bought "a supercharged corvette". It's called technology. You will lose you *** on money spent on new cars with depreciation if you just buy the next best thing.

Plus, beating corvette's in a 16 year old car makes me smile knowing I spent a fraction of the money Doing more with less.

Steve,
You are sorely mistaken if you think the amount of money spent on the UMI car is equivalent to a new supercharged vette. That makes you a uninformed idiot IMHO....there really isn't a better bang for the buck out there for road course/autocross fun than a 4th gen f-body. If you haven't figured that out yet, then where have you been, son ? I've owned a new Z06 and my 4th gen is waaay less expensive, with all my mods similar to UMI car. But, what do I know ....just my .02 cents

Just another intelligent, insightful, and useful post full of great technical information from Steve c. He is truly an asset to this community. Without him, I would have never known that a supercharged corvette was equal in cost to my 15 year old Camaro.

Thanks Steve! Can't wait to hear the interesting insight you have for us next.

not having airbags fails state inspection and i dont think there is anything in the book about a roll cage. ill check and if there is ill edit this post with it

First engine part has arrived, a set of AFR 215 LSX Mongoose heads. This is our 2nd set of AFR heads and we have a 3rd set on the way, awesome heads and awesome people to deal with.





Also here is a great example of why bearing mounted shocks should be used over poly on racing applications. For street the poly is nice, for any type of racing you can see how the t-bar is moved and the poly bushings are bulging. We will be upgrading to our new front coilover kit with bearing mounted upper and lower shocks. Stay tuned, we have some cool new stuff coming.

Hey guys, make sure to call up Improved racing and get their pan baffle so the new engine lives a happy life. While your at it they have an excellent crank scraper and of course a big oil cooler is a good idea with the abuse this car sees. I'd be willing to bet the engine failure was related to oil starvation.

Maybe so, but even when I was in Joyzee, when they actually had nitpicking, draconian, 'big brother' type inspections, I went right through for 13 years without a driver's side air bag, and like I said, for the past 3 years in Pa.

So maybe the private inspections in this state are much more intent on trying to find other, more expensive things wrong inspection wise, which will bring them in much more coin for them hoping the owner will get it fixed there?

dailydriver

Will you ever go to either Koni yellows (with a coil over kit), or the 'real' road race (but stupidly priced) Penskes or such??

No matter how great a spherical bearing you use for the shock mounts, they WILL eventually knock like the proverbial jackhammers on the street, especially on THIS state's roads, or at least what they call roads here.

I know, as I had the LG Bilstein alloy bodied coil overs with Hyperco springs ALL AROUND for a couple of years, and I must have replaced those bearings every 6 months, and even the new ones rattled and knocked on the just as poor Joyzee roads.

Don't know about Steve but I'm digging the progress. To each their own

I'd like to see a set of KWs on the car, hoping they don't go the viking or qa1 route. Or, Or if they found a way to make a better top mount for Konis that would be dope too.

EDIT: forgot the car already had vikings until I looked closer at the picture.

Amused and extremely impressed by how the car looks and performs with the Vikings for autocross. Nothing bad against them personally, yet true autoXers seem to give those shocks the death ticket when it comes to handling because they aren't a gas charged shock and/or twin tube, not sure which one it is. Apparently Vikings don't work for handling because 'more adjustments does not equal a stiffer and more competent shock.' I have to say though that UMI proved that Vikings can be manipulated very well for them to be able to place in the standings that they placed in with those shocks in the events they used their car in. I honestly with probably many others here would like to see you slide the classic Koni/Strano setup under there and see the time difference back to back to really see, if any, the difference a gas charged shock does vs a drag shock does on a course.

Love the decals and stance by the way, adds the renowned sponsorship to the car that makes it look official and stuffed with badass performance!

UMI Tech

You just never know what's gonna happen with shocks.



Also, we go pretty fast on Vikings.

I'm not going to say you can't go fast on vikings. I will say that I think you're leaving something on the table, especially with your caliber of drivers and the other mods on the car. Ok back on topic now.

smitty2919

With the money spent on the motor and the rest of the car, might as well bump up the caliber of shocks. Or like others have said, run a more common autocross combo like the koni/strano.

GNC Rick

Yes another vote for Koni/Strano set up....single adjustable Koni that is.

Noticed you switched to the boxed lower arms. A good idea.

Here is another vote for the Koni's.


As for the wheel bearings, I am trying this set up out. SKF X Trackers.

Thanks for the info on Improved Racing. We have been looking at road race pans so this might be a great option. And yes I agree, we would be sure this is the reason of engine failure as well. Also oil temp seems to be a huge issue on the LS engines so looking at coolers as well. Any suggestions?
