Hi Aaron
Car is imported from Florida to Switzerland and from there to Finland. This car was really rusty. One of the reasons to do this extensive suspension fix was that my car was wrecked and tub was 50mm bendt in front. I think i will need to find better tub to start my full on race car (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Well, maybe i'll do a Porsche B32 replica first (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) That would be something else for Finnish Roadsport Class.

BTW Aaron, your car looks amazing with the new paint, not that it was ugly before.

I am enjoying your project very much. I wish the SCCA would allow us to change these things for production.

I only have one comment, if it is okay, It appears you have just placed the shocks on the rear suspension for the photo purpose, but if they are mounted in that manner, the unsprung mass will increase. If they are mounted with the shock body mounted to the chassis and the shock shaft to the suspension.

Keep up the awesome work, I am looking forward to future pics.

Thanks for comment Erik.
What would you do? We were thinking about the inline arrangement with pushrod's but thought that we should leave something to do for next winter (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) .
I was going to attach the shock body to suspension and shaft side to chassis, but i can still make it other way if it's wiser.
Btw, do you know how much should i use bumpstop with these Koni's? I figure that it's enough if i just put so much that the shock doesn't bottom?

Mika,


With pushrods it over complicates things, unless your packaging will dictate you must have them. As far as Iam concerned pushrods will only be a benefit for two reasons.
- suspension package is in the airstream, and yours really isn't.
-Suspesion package needs to be adjustable with regards to spring/damper progression.

My suggestion on your set up is to mount the shocks with the damper shaft attached to the lower a-arm, not the upper. This will also keep the mass lower in the car. As for the rubber bump stops, they really need to be installed, and I woudl suggest determining the final placement of the upper shock mount after you (maybe you already have) determine what the travel will be and where ride height will be. Then have the bumpers come into play in the last 10% of the travel. This would be my suggestion not knowing exactly what you have.

Now i understand what you mean. I need to attach the shocks to hub part. Those balljoints are not strong enough to attach shocks to arms. Arms are also designed so that they can't take the powers from shocks.
I'am trying to attach those as low as possible.
Thanks alot for your comments, i really appriciate it.

It was nice sunny day and +10c so i painted quarters outside.

First coat of blue is on (front is still unpainted)
Next light skim of bondo and final paint.
Engine bay is ready for engine.

Ok, there is some brackets still to be welded and couple of places where the tub is welded to table needs to be painted again.

Jeroen, i got the font and now Callicott Msport logo is ready, thanks.

Troubles! Need to make new a-arms. Someone (me) did a slight 80mm mistake when measuring track width (from bearing house to bearing house).
Oh well, the new ones will be made of tube. Front is ready and even the steering shafts are moved to trunks side.
No problem in front with 225-50-16 tires.

Mika

Not much interest here (IMG:style_emoticons/default/smile.gif) I think well call this thread dead, but before that here is some pictures.
Because of lot of things i did not complete my car before first race. Now we have one open class race in next weekend and we are going to give the shakedown in there. We haven't been able to drive in a track at all so it might be stupid to even go (IMG:style_emoticons/default/confused24.gif) Next official race is in 8th of next month but we are going to get a new baby in 6th so i won't be able to go there. There is lot of things that needs to be finished but we'll have the new look ready before Historic Grand Race (thanks again Dan and Jeroen).

Hi guys
New suspension feels different. Steering response is much much "tighter". Now i can say that it feels like go-cart. Aaron, the front is actually still 2cm too high, rear is in its riding height.

Rear springs are 82kg/cm at the moment. We started to test it with 45kg/cm which is about 250lbs/inch. These springs are the 5th that we tested and these are quite close to final. Shocks are Koni's aluminium ones with double adj.

Front is the one that i used last year. Just raised it 7cm to correct the steering geometry to original porsche specs. 22mm torsion bars and 25mm cromoly sway bar. Front shocks are Spax's from England.
I'll add some pictures later
