New member - here from New Jersey - F-Body Road Racing and Autocross Forums

Hi guys. I recently became aware of this whole board via some friends of mine on thirdgen.org. This looks like a good forum for me to be on and I am hopeful to learn as much as I can by reading some of the forums. I will make sure to search for the info I have questions on, and I will always keep things tech related.

I've had my 1987 IROC for 21 years now and it was my high school car. Years later after I made it look real nice, I got bit by the quest for more performance. The car is indeed a true real-deal street car that I use for autocross, short course road racing, drag racing, car shows, and general street duty. I do not own a trailer and street drive it wherever I go. My parts selection is based on those factors, so I have quite the balancing act to do when it comes to picking parts.

I have competed in the Optima Batteries Search for the Ultimate Street Car series in 2016 and also in 2017 (both at New Jersey Motorsports park)
I have also competed in the UMI Performance Autocross challenge in 2019 and 2020.
I also have done a handful of other autocross events in NJ and PA as well.

I enjoy the heck out of the car, but I know it will never be competitive in any specific CAM-T class or competition. For me, it is all about building/driving the car to find its potential, and then learning what I can do to take it a step further.

As mentioned, its an 1987 IROC-Z. It has a 406 small block chevy with a dart block, dart heads, callies rotating assembly, full roller valvetrain, and I use the holley sniper efi. I know the automatic trans is not optimal, but it is what is staying in the car. it consists of a ProBuilt Automatics 700R4 built with their tiop level package, and a 9.5" Edge Racing 3,400 converter. A 3" driveshaft from Dennys, and a Moser 12 bolt rear axle with 33 spline axles nad a tru Track. It currently has 3.55 gears, but In February it will get a gear change from 3.55 to 3.91 gears. Also, the engine was built with nitrous in mind and it will indeed be getting a 150-200 wet shot soon.

Front:
I have the C4 HD 13" brake package up with Hawks HPS pads. UMI A-arms up front with Koni Yellow struts and UMI upper strut mounts. OEM sway bar with poly mounts. Replacement Moog springs and a 2" drop-spindle setup. Replaced everything to the steering system with new components and had the original IROC-Z steering box re-built this past winter so it is very on-point. Wheels are 18x8" with a Nitto 555 255/40/18 tire that I would love to replace.

Rear:
UMI adjustable lower control arms, UMI panhard bar, Founders performance upper panhard bar. OEM swaybar with poly mounts. Koni yellow rear shocks. Moog springs with 3/4 coil cut off. C4 rear brake conversion so 12" rotor with powerstop pads. 18x10" wheel with a 285/40/18 nitto 55 tire. Also looking to replace these in the spring.

Here are some photos:

I also have a youtube channel, and while I do not do any editing or creative video work, I do have some videos of my autocross runs over recent years. if you search through the "My videos" section. My username is the same as it is here IROCZman15

I am also on www.thirdgen.org using this username and I have a couple of long "build" threads and some racing info there along with photos, datalogs, videos, and tech info.

Glad to be a member here and looking forward to what I can learn after I spend some time reading.

I'm pretty used to these sway bars and at this point I think I am leaving them as is for a while. But what you are saying does make sense to me mike: cool. yea. Even if I ever do get a trailer, the main concept of this car will always be a street car. perhaps I will have another car one day that is a track beast, but just not this one. I have not made it down to Virgina for any racing events. Maybe one day I can! slow: Ah! thats right! we did meet at the Giants Stadium event, I think that was 2018. In fact I think during the early morning drive there we were both on route 80 east side by side for a little bit. Glad to re-meet ya then.

I don't like mods that take a perfectly fine street car and make them evil on the street. Having been around race cars, it's better to just admit you want a race car and buy one separately. Especially since used race cars (that aren't done wrong) can be such a good value. Of course for me that comes with a truck and trailer bill though since my truck is a 4cyl 1st Gen Colorado.
