Hello all i have finally started to work on the fiero again. It all started with this vision of a twin turbo v6 rear engine beast. Now i know some of you say that's over kill, i actually agree, that's why im building it. This is what the car started out looking like.
And this is where it is now. The interior is almost complete. Only have the center console to finish. I will update as the progress moves along.

I'm looking forward to watching how this progresses.
You should use PIP (Pennock's Image Poster - located at the bottom of the page) for posting all images. Better than people having to follow links, plus no risk of the pics suddenly disappearing later on.
The next thing I am moving on to is the suspension and brakes. Are the 88 rear adjustable trailing arms really make a huge difference or should I stay with the stock rear trailing arms and add Polyurethane bushings. In the front I am going to change everything over to the Polyurethane on everything, new sway bar end links, new tie rod ends, and new ball joints. To add to the suspension I am going to do coilovers on all four corners with the koni yellow shocks and 400lb springs in the front and 300lb in the rear. Then I am going to take stock 88 front sway bar, move it to the back and buy an aftermarket sway far for the front.
For brakes, I'm kind of torn, are the stock calipers really not that great. I was thinking about doing the stock calipers all around but adding EBC yellow pads and cross drilled and hatched stock size rotors and stainless steal brake lines. This unit already has the over sized brake master and booster.
I will be doing new rear bearing hub assembly and possibly the front drop hubs.
What do you guys recommend I do different or what is a better set up.
One of the lateral links (not a trailing arm) in the 88 rear already has a turnbuckle for length adjustment; I would think that the factory setup would give you the necessary adjustments to perform an alignment.
EBC pads is a good idea. SS brake hoses are questionable, I would prefer to install new rubber hoses. I would stick with 88 calipers and rotors, then if you're not satisfied, change to something else. They're already considered "big-brakes" compared to the 84-87 brakes, so you may not need more.

Coilovers on front will require new or modified lower control arms. The stock control arms shock mounting points are not able to handle the spring pressure. The stock suspension is actually really good, on both ends of the car. Fieroguru has done a lot of modeling and has developed 88 specific parts to improve handling, especially when lowering the car. Your spring rate selection is awfully high unless it is specifically destined for track use. Corvette rotors/88 callers is a good upgrade over the stock sized rotors, especially if you are going with larger diameter rims and wide low profile tires. The addition of a rear bar is a great upgrade. I'm not aware of any aftermarket bars for the 88. You will want to find a stock 88 rear bar. Good luck with your project.
GMs approach to handling for years was to stiffen and prevent roll, while the European designers paid more attention to good suspension geometry throughout suspension travel and kept the spring rates soft, allowing body roll. Neither was totally correct, we now see a combination of both philosophies, and the addition of variable rate damping. As long as the car is balanced, handling will be good.
Thank you everyone for the replies. The reason for the high spring rate in the front is for track use. I want the springs to transfer the weight to the rear at acceleration and absorb weight when stopping. I just realized I can not do coil overs in the front, I was kind of thinking about that when I couldn't find anything on them. I want to lower the car a little bit maybe 1.5 inches, I'm thinking the west coast fiero coil over kit may be best.
For the rear I can not find an aftermarket sway bars, that's why I thought people said they use the 88 front on the rear and buy an aftermarket for the front. If that is not the case, I will try and find an 88 rear sway bar. There really are not to many intermediate suspension mods for these cars, what I mean by that is there are full track set ups and full street set ups, what's in between, stock? I want to make this car fun on the track but also street able.
The street tire set up in the rear will be a 10 1/2 wide by 19 or 20, The reason for such a wide tire is I want to do either the IMSA kit or the V8 Archie wide body. I am torn between the two, the big factor here is do I really need to spend 5k on a body kit, probably not. For the front I will do 1 size smaller compared to witch ever rear I choose. The tires will be R888s all around.
Transmission is going to be an f23, this unit is already purchased.
Engine is a 2001 L36, this engine will be 100% built, not an inch untouched. The reason I went L36 is because I'm going to rebuilt with forged parts anyways and not use the supercharger, so why buy extra parts I don't need. Exact details on the engine are still up in the air based on I do not know what exact parts I want to use yet. Which turbos are really the hold up.
Again thank you all for the input, I will add pictures (the right way) as I stock to move forward. All of you here are great help and very knowledgeable, I have learned a lot learking around here. Not like other car forums I am a part of.

I have finished purchasing the suspension components.
