if you go to jegs.com put in your year make and model. then, search for "spool". it gave me 4 different mini spools. do you have 26 spline or 28 spline axles?

with the coil overs up front, did you reinforce the strut tower since they are bearing the entire load of the front of the car?

Al Weyman

It has standard axles I would assume, 26 spline? I used the complete Spohn kit with the big extended and reinforced top towers never botherered to reinforce the fletch panels but from memory I think they supplied a plate that goes underneath and I would have fitted the kit as per their instructions.

If Jegs can supply I well try a spool I am just worried about breaking axle shafts. I have attached a picture that has appeared on the net of me chasing down the '917'. It looks to have a fair bit of roll which I am quite surprised to see considering it has heavy duty IROC-Z bars front and rear. The red white and blue stripes were to mark the royal wedding as asked by the organiser, not my cup of meat though!

I can't offer any advice I'm afraid but would like to know what class/championship you race in. Not every day you get the chance to see a 3rd gen racing over here, especially around corners!

I road race my 3rd gen and if you are running subframe connectors and a roll cage you need a smaller sway bar or none at all. I disconnected mine at the track the last time out and what a tremendous difference. For the 5 minutes it takes and no cost, give this a try. It will definitely help to keep that inside rear tire planted coming out of the turns. You should be accelerating at or slightly before the apex so while the body is leaning, the sway bar is lifting that inside rear tire. Try disconnecting one link next time out there and if it makes a difference, remove the whole bar. free and easy to do

Al Weyman

Yes I may well try that especially if I have to use the car at the next meeting on the 18/19th June at Mallory Park as that is a circuit that really exagerates the problem. I am planning to take the 2nd Gen (sans rear A/R bar!) but am fitting a new clutch and not convinced (havnt actually started it yet) that its going to desengage correctly. The 3rd gen needs heads popping back on as I got a leaking head gasket last time out but that shouldnt take too long.

@ Burns, I race with these guys in the Pre 93 championship, the picture above was at a scratch race earlier in the year to support the brave organisers of a 6 hour event who hired Snetterton circuit at great personal cost and that I couldnt do the 6 hour. It was a 30 minute race and quite fun actually although problems meant I didnt get anywhere but I did finish. Here is the link to my regular club http://www.csccgb.co.uk/

My wife and I both run road courses and have both had that same problem. Our home track (V.I.R. Virginia International Raceway) has many nasty turns and we were pulling each others hair out trying to figure out how to get better response and hook up out of the turns. We tried everything on her 89 Camaro and spent a ton of money with no positive results. On my 92 Camaro I decided to try some wider tires and wouldnt ya know it! Bam! I was grabbing like a purse snatcher out of the turns. We put some wider tires on hers and same results. So the first thing I'd suggest is looking at your widest tire options. That'll make one helluva difference! Good luck!

I have a 275 x 35 x 18 on the rear squeezed on to a 9inch rim and thats as wide as the regulations will allow unfortunately. Has anyone used a spool in these cars?

Al Weyman

Here is the vid form the sports vs sallons none championship race at Donington. If you listen carefully you can here me backing out the throttle and getting into top gear asap to try to eliminate wheel spin. I was way down the field as it rained hard in qualifing and this car doesnt like the wet much! http://www.youtube.com/watch?v=UwvYgHygVEE

I have this one, not tuned yet so I cant comment on performance of unit.

If you search thru Jegs or Summit you can also find stronger axles for your stock housing.
I ran a 7.5 housing in my circle track car with upgraded axles. The axle bearing were my weak point after that.

Tires nitto drag radials hold amazing I had 550hp with a six speed and they held amazing they are amazing in a straight line and just as good in turns I had them as my daily driving tires and would hit over 130 daily on the way to work

you do not want a locked rear because then you will loose it in the corners but upgrade you diff and maybe lower your gear ratio just a tad if you have the power then spread it out and use more skill to pass than muscleing past

Also dont floor it if you know you will spin lightly lay into it and you as the driver drive the car and dont let the car drive you

I have a new Eaton I have bought from a member on its way here plus some Moser axles half shafts and bearings and a panard realignment bracket. Alos I have cut down the Spohn supplied front springs that were simply too long so I couldnt adjust the corner s properly and have been doing that today and all is looking better.

Al Weyman

Raced it at the weekend on a pure handling circuit, well correction I qualified it but got thrown off the grid because power steering pump was leaking oil. Anyhow the bottom line is its like a different car and handled like a big Go kart. She hooked up well out of corners and I could induce power oversteer very easily. Its a differnt beast now and I need a few more sessions to get the most out of it but found I could brake a lot later and go deeper into corners as it just clung on in there. Well pleased and there is more to come.

AM91Camaro_RS

and that's from doing all of the things you mentioned in the previous post? glad it helped!

I cut down the Steve Spohn supplied front coil over springs something I should have done several years ago when I first got them but being reluctant to cut down new springs and assuming they knew best I left them and tried to balance car out with the rear coil overs. This for a start had a massive effect and I could straight away balance the car better with the adjuster ring on the back coil over dampers visably where it should be about 1/4" up on the drivers side to compensate for my weight and even with out weighing it but just measuring from the lip of the wheel arch with weight in the drivers side it sat on the ground so much better. There was about an 1.5" difference in the adjuster ring from side to side before I started so this was like a three legged stool!

During doing this I discovered that the Koni front struts I bought years ago in a breakers yard and had revalved to Firehawk racing spec by Koni seemed very soft on what I thought was full hard. I first thought they were knackered till I turned the adjuster ANTI-CLOCKWISE and to my horror realised since I built the car in 1990 I had been running them fully soft!!!! I never got the little yellow adjuster **** when I bought them and assummed clockwise would tighten them up like every other shocker I had ever worked with but no!

Then I checked the tracking and it was tracking miles out on the front at least 3/4" although I did take a minor blow on the side at the last race and had messed with the front suspension so that may have been why.

I then moved to the rear and realised I had adjusted the two way adjustable QA coil overs I had been adjusting the bump for rebound and visa versa Duh again!

The Spohn rod ended Panhard bar was running about 6 degrees out of line so I fitted a Jegster realignment bracket and moved that to the second hole down which made it level.

Then I fitted the Eaton diff I bought from a member here (thanks for shipping Roy) and remarkably it went straight in with 8 thou backlash and the pattern looked OK so I ran it and do you know what I had a bonus. There were some noise coming from the rear if you see any of my videos after I originally had fitted the 3.73 gears a while back, well all that noise has gone but as I also replaced the diff and outer bearings and fitted Moser 28 spline shafts (upgraded from the 26 spine OEM ones) who knows why that is maybe just good luck and the gears are meshing slightly better.

Finally I readjusted all the sway bars to take any set out of them and they were obviously miles out due to the previously unlevel spring settings.

Anyhow I know it was too much to do in one hit and I have some fine tuning but at last it looks and feels like a race car and is definitely quicker than the 2nd gen I race. Next meeting is at Rockingham (UK) 2/3rd Oct and the only US style oval in the UK and predominately left hand bends so I may go reasonably well there.

Very nice thread and lots of info! I had no idea about the panhard bar relocating piece and what a difference it makes. That's awesome! Glad to see you're car is progressing!
