Mostmint Racing 1989 Corvette Build

Thanks! We have had a few hurdles but we finally made it. Nothing like the felling of success when we took he checked flag. We were super happy with the car, the tires and brakes held up and still have life. That was refreshing to know as other cars were burning through tires and brakes.

The engine temp sensor is not working and the oil pressure is reading high (used a mismatched sensor) so we acquired gauges. Now have five gauges to install.
the car sits high about 1/2” in front and 1” in the back. Measurements compared to drcook’s car which I would consider a good representation of stock ride height.
Did some research on the Rhodes roll cage. It is generally not shaped the way I want around the A pillar and in the door bars.
Acquired a headlight bezel and the frame to k frame brackets.
Took some time to organize the garage since I now have to store parts for two race cars.
I have a few pics but today I can't get them to upload. Will try again later.

in regards to ride height, i wonder if the traditional z51 handling package would end up being too stiff given the reduction in weight. makes me wonder if a softerspring would actually be better when lightening up the car significantly.
thoughts on this?

We have z51 springs in our car and even with the lowering kit our car still sits a little high. I think it’s a result of weight reduction. Looks like that’s what’s going on with their car as well.

I believe softer springs are going to reduce responsiveness to steering input and to weight transfer. There will be more wheel/suspension travel as well.
In general those are not qualities I think I want but as I learn more about Vettes I may change my mind (like do they have progressive camber gain on front suspension compression?). The Saturn has camber loss under compression so I want the stiff springs. So much to learn still

$50 of parts from a local guy who is using C4 Vette suspension in old pickup trucks
Previous owner installed option. Please keep the torpedo heater away from the rocker panels
Moved the car around the other day and found these on the drive. Not sure where they could have come from. Shims for front upper control arms seem to be all there and tight

Updates since last update:
1) Made significant progress building a temporary gauge panel - will house gauges for engine water temp, engine oil temp, trans oil temp, engine oil pressure and air fuel ratio. Factory sending units for oil pressure and engine temp gauges not working
2) Installed the RF inner fender center section. Took a bunch of fabricating since the part we had was from an earlier model and GM changed the part.
2) Fixed the targa top it had some bolts loose on the support bracket at the top of the A pillar.
3) Replaced the RF headlight frame (discovered the headlights pop up OK but they don't come on)
4) replaced the melted right side rocker panel
5) installed the new master cylinder
6) installed cradle to frame brace on LF - this was missing I had bought one finally had chance to install
7) more prep work on the exhaust manifolds for the straight plug heads - the EGR ports welded shut, studs removed, drilled and tapped, clean up some obstructions in the pipes. These clearly provide more room for the plugs
8) got license plates yesterday. Hoping for a road test soon.

1 Installed the heat wrap on the straight plug manifolds and put them in the car
2 Installed the temporary gauge panel and hooked up all but the oil pressure
3 Got some help from a friend to locate a fiberglass top 86 1/2-88 style, and picked up brackets to install
4 Temporary reinstall of passenger seat
5 Test drive #1 uncovers the car track straight, stops straight, shifts good. Power is not overwhelming, the fan is not kicking on, and the gauge panel power goes off when you press the brake pedal.
6 Removed radio antenna, rear shade, heater core, air ducting in the dash, lots of wiring – everything in the doors except power windows, all the radio wiring, heat/AC control wiring, VATS, interior courtesy lights, door chime, evap canister. Shorten the ABS wiring. There was a lot of time hand picking through the wiring harness
7 Fixed the power source for the gauges
8 Second test drive uncovered all of the calipers are sticking. After < 10 minutes drive around the block the front rotors were at 600 degrees. Still not sure if I want stock brakes so getting some remanufactured calipers to fix it
Can't race with arcrylic top
Lots of wires out of the door. Keeping the power windows for a little while longer. Focus now is eliminating unnecessary wiring as items to simplify that work
This update reports 33 lbs total off the car with a few parts not weighed
oil gauge not hooked up yet. from the second test drive

As the car reached it's 1 year anniversary with me I wanted to provide an update.
Very little has happened since last update as I am busy with life and prepping the Saturn for upcoming track day. I had made a shopping list for Carlisle but ended up sick so I missed that event.
I have new front calipers, a poly bushing kit for the suspension, an actual Wix air filter (it had no filter in the housing). Rear calipers should be here soon.

I gave him a set of low mileage Z51 Bilsteins off my '96. I put new ones on mine. Last time I was at his house, it was progressing.

I had to set this project down as we went racing with the Saturn at Indy, and we are racing again at Nelson Ledges this weekend. Add in a bunch of other life things and the car waits. I have burned many cycles on my Saturn so I will need a few weeks off. Come October I think this project will resume. Hoping to get a few drag strip passes before the snow flies.

Looks like work is to resume on this car
Updates:
1) Thanks to my brother a set of four 285/40/17 Conti's are in the garage. They are used but at just 5 years old and with decent tread they should work for drag racing and maybe a track day
2) As I may have mentioned earlier the calipers were all sticking. I have the fronts, but the rear calipers are not available anywhere right now. No cores mean they can't be remanufactured. Going to have to do rebuild kits
3) Compiled a list of to do's to get ready for a drag strip shakedown or a track day. Track day will be light use due to lack of beefed up transmission cooling, lack of brake cooling, lack of proper oil pan baffling/accusump. Track day on 11/2. Still lacking all the endurance upgrades so this will have to be a light test. Drag strip open Saturdays through November so there is a good chance it'll be ready for that
4) I acquired a set of C5 calipers and rotors for $50. Was going to turn these in as cores, but might end up converting over to C5 brakes just for parts availability. Will weigh the parts to compare. Have confirmed the 17" rims will fit over base model C5 brakes.
Going to acquire wiper arms, rear caliper rebuild kits today, maybe a few other odds and ends

base and zo6 c5 are same, fyi, other than paint colour
what are the point rules as far as deviating from original rim/tire sizes?
im very interested and rooting for you making that automatic work!! a nice exploit if it does.

isnt there a penalty/points cost for brake upgrades?

I could easily run 18" wheels on the car but I'm trying to keep down weight and cost.
