Re: 1988 Fiero track car
Since you're moving forward with wheel/tire/suspension parts selection, do you have an idea of what your weight distribution will be like, even though your engine isn't installed yet? There are some other K-powered Fieros out there, so maybe those folks can tell you their weight distribution. There...

Re: 1988 Fiero track car
Some more progress, mostly gathering parts. I've had a couple long phone calls with Chris over at West Coast Fiero sorting out the suspension and brake parts. I picked up the engine that will be going in, a K20A2 out of an 03 Acura RSX type S. Came with the 6 speed transmission, shifter, cables, wir...

Re: Stronger front 88 bearing/hub options
Just a quick update from me - I did order a set of the Coleman racing spindle adapters for my 88. Picked them up this weekend. They look very sturdy. As draven mentioned, the hub section does extend quite a ways through the wheel, and require a 70mm center bore on the wheel and brake rotor (standard...

Re: 1988 Fiero track car
Little bit of progress. I've been quite a while researching and gathering parts. Due to various delays (covid, natural disasters, etc etc) I am currently still waiting on engine mounts to start that part, and various suspension components to start that side of things. However, I've grown restless an...

Re: The Mule rides again (sort of) - pics.
I did the whole underside of my Mitsubishi Evo rally car in POR-15 (when I still had it), followed all the prep steps and sprayed it on with an air gun. It made a heck of a mess applying but it held up really well for a few years of rally on both gravel and Canadian ice and snow.

Re: Double Adjustables on a Fiero??!!
More options is always good. What kind of spring setup would you be planning to run with these?

Re: Runs rough. Giant sucking sound from intake.
Sucking noise to me means air is being forced through a restriction somewhere in the intake system. I'm not super familiar with the plumbing on a 3800sc, but I had a somewhat similar issue on a C4 corvette when one of the intake hoses got old, it would start collapsing under throttle, make a sucking...

Re: Stronger front 88 bearing/hub options
The separation between the two bearings is actually the big factor. Rodney's bearings are on the right rack with extending the back side of the cartridge toward the spring in order to increase the separation between the inner and outer bearings. (I wonder where he got that idea! :grin: ) Rodney's a...

Re: 1988 Fiero track car
Oh, yeah, sorry, intonation over text. I was impressed that you would be able to fit so much tire, not trying to say it's not necessary. No big deal... I've just heard people spout the idea that tires can be "too big" for autocross or time attack. 285/30's are a great tire for 18x9.5 whee...

Re: 1988 Fiero track car
Yeah, I have every intention of shelling out for 2 piece rotors to keep the unsprung weight down, but these brakes need to be 100% trustworthy to turn good lap times. I figure if my C6 Z06 has a 14" rotor up front stock (and 13" rear) and I consider it just acceptable but not overkill, th...

Re: 1988 Fiero track car
Very interesting. What's the advantage of keeping the OEM lower with the rod-end conversion over going to a tubular lower arm? There's not a lot of gain in terms of unsprung weight reduction to be had from going to a tubular lower arm. The OE lower arm is structurally efficient, but does need to be...

Re: 1988 Fiero track car
I was impressed with how light FieroGuru's car ended up... I think he started with a no-option '88. I'm trying to be realistic with weight expectations, given I'll be adding a full cage I expect most of my weight savings by stripping the interior and getting rid of the boat anchor engine will be ca...

Re: Stronger front 88 bearing/hub options
Update: I've contacted Coleman Racing and they are indeed still able to make the spindle conversion kits for 88 Fieros in 5x100. It's around $500/corner. I've also been looking at Rodney's new design, rebuildable hubs. I think this is a new revision since the initial tapered roller hubs that I've se...

Re: 1988 Fiero track car
Welcome! You're off to a great start! Looking forward to seeing your car take shape. The '88 Fiero has hella potential, but it's hardly ever realized, much less publicized. How much have you read on this forum? Tubular upper arms are way more work for less adjustability than some much easier design...

1988 Fiero track car
Background: I've been doing Time Trials in sport class with a lightly modded 2009 Corvette Z06 for a couple years and I'm getting bored of it. Not the racing, that's always fun, but the car. I want to build something different and interesting. The end goal is to have something around as fast as the ...

Re: Stronger front 88 bearing/hub options
New member, curious, did anything ever come of either of these ideas? Either the custom uprights or the coleman spindle conversion? I'm working on an 88 Fiero track car build and it seems like the wheel bearings are the main thing holding it back, everything else is more or less solved. I'd love to ...
