Tech Tips, Tech Questions / Re: Doing my clutch. Cradle is out. What next?

« on: August 27, 2018, 12:18:22 am »

I used Rodney's ball joints. (Standard. Not lowering)
They come with a big spring clip that can be used to hold them in place in the control arm.
Since I had to press/pound mine in, I didn't bother with the clips.  I don't think they're going anywhere.

The clips are there for safety for cases like mine. The clips are preventing the ball joints from coming out at this point.

Tech Tips, Tech Questions / Held/htc motorsport front end kit?

« on: August 26, 2018, 06:53:36 pm »

My lower control arms appear to be done as the balljoints can slip up and down now. With the cost of replacing the lowers and ball joints i was looking at held motorsports front suspension kit with tubular control arms and adjustable shocks. I autocross my car and do mountain runs so id like the adjustability. Ill stick with stock spring rate for now until i get a koni red coilover kit for the back.

Are they still in business and has anyone used a kit from them? Ive wanted to have an adjustable suspention and now may be the time. Too bad i wont make RFTH.

Got it done! Everythings much better now with new mounts and the clutch. Now its time for my front end. The balljoints are slipping in the lower control arms. Probably cant have that done before RFTH  ill start a new thread for that

The fiero works... but the clutch is almost gone!
I just ordered the fidanza aluminum flywheel and the comp clutch i posted about, they need to go in asap!

I could probably cruise there! Clutch is slipping on pulls but it still cruises fine.

Tech Tips, Tech Questions / New clutch and flywheel. is this correct?

« on: July 07, 2018, 03:45:55 pm »

Time for a new clutch and flywheel! I was looking into stage 1 clutch options as I autocross and do mountain runs a lot. This comp clutch has better friction without having any extra pedal hardness or degraded engagement smoothness. However I cannot find it on their website. Will this clutch work if it works for an 88-91 grand am?

Getting an aluminum flywheel too, this should work aswell?

Tech Tips, Tech Questions / Re: Fiero steering column

« on: February 04, 2018, 05:37:25 pm »

Yes, it matters, although the column can be modified.  It is possible that the bolts on your column are just loose.

Its not the tilt that has play it is the steering itself!

Im needing to replace my column since theres about 40 degrees of steering play in the tilt joint. Havent rebuilt one yet so im going to put a new one in for now and rebuild my old one. Im looking at columns on ebay, does it matter if it comes from a manual or auto car?

General Fiero Discussion / R1 concepts rotors 88 gt

« on: December 09, 2017, 05:52:30 pm »

Hello all, I am looking for new rotors for my 88 gt and am looking at R1 concepts slotted eline rotors (non-drilled). Anyone used these before? I am wondering If they are vented like the stock rotors because I cant seem to find any pictures of the fiero specific rotors

Tech Tips, Tech Questions / Steering axis inclination, included angle??

« on: February 03, 2017, 12:33:19 am »

This is very technical so here goes nothing.

I am trying to calculate what camber my wheels are at at a given toe (steering angle the wheels at) to assess whether i want more caster or not on my 88 gt. (I'm a Mechanical Engineering student so I love to get technical with things)

I have the equation to calculate it just dont know what the fieros steering axis inclination is supposed to be? its supposed to be (included angle - camber) where included angle is the angle between the steeting axis and the hub face (plane of rotation of wheels).

Its as follows:

Sin(C)=(Cos(Co)-Cos(C)Cos(T))Tan(S)-Cos(C)Sin(T)Tan(K)+Sin(Co)

IA=S+Co

Where

C=Camber
Co=Camber at 0 toe. (straight ahead)
k= caster
S=STEERING AXIS INCLINATION
T=Toe (Relative to straight ahead)
IA=INCLUDED ANGLE

All I need is steering axis inclination or Included angle. Included angle is literally just the angle between the steering axis and the hub face.

...anyone?

Mine (88 GT 5 speed in red)

With a few minor tweaks including...

aluminum LS
performance tires
replace all bushings/wear parts
fresh paint including fixing overspray
sound system (SQ not SPL)

but its still my dream car anyway... at least one of them!

Tech Tips, Tech Questions / Good alignment near upstate SC? your alignment specs for 88 gt/formula?

« on: October 18, 2016, 12:11:07 pm »

Hey everybody, looking at replacing the inner and outer tie rods relatively soon, hopefully around the holidays when school is over. The steering feel is not laser tight like I want it. After replacing this I will need an alignment, plus my alignment isn't great as is and would like the tires to last a bit longer.

I figured while I'm at it, I'd replace the rear struts since I have a set of kyb's laying around, and do the front shocks too (Im getting the fiero store abjustable camber bolts for the struts). Is there anything else worth doing or replacing before getting an alignment, or simply while I have things apart? Anything else that needs replacement over time to tighten steering and handling? (thinking about upper and lower ball joints and new steering rack mounts while Im in there) Once I've replaced these things, it'll be time for an alignment. I understand how fieros are aligned (atleast the 88's) and that the fiero alignment can be tricky. I'd love to do it myself but dont have the equipment, and would like it to be more precise than a string alignment.

Where do you guys near the upstate SC area (or in Georgia) get your alignments done, and are sure it's done correctly? I've heard about places not doing the proper jounce procedure, just plain getting it wrong, or failing to torque down everything correctly.

Lastly, what alignment specs do you use for max performance and feel on a stock 88 gt/formula? can we reduce understeer without making lift off/snap oversteer worse?
I believe I want to max out caster at 5 degrees, for the feel and the effects it has on dynamic caster
What about front and rear camber?
toe in front rear?

I've read a bit about non stock performance alignment, but was curious what you guys ran
