914R build thread revisited, Latest transformation has commenced Options

[campbellcj]

Some of you may have seen my earlier build thread on the 914club site. In a nutshell I have a 73 2.0 that I converted to a six in 2003. It's now heavily modified and race-prepped, powered by a stout 2.7 twin-plug engine.

The car currently weighs 1988lbs without fuel or driver; my POC minimum class weight with gas and driver is 2209lbs. It's still narrow-bodied and I am running 16x7 Fuchs with 205/45 Hoosiers. As you might guess, the car is significantly grip-limited and traction-limited in the rear especially. It basically tears the tread off R6's within 6 run sessions or so.

Here is its current state:

I just dropped it off at a local shop, about to dive into:

- Tangerine Racing steel flares, front/rear
- Sheridan 6" f/g rear spoiler
- Rollcage triangulation to suspension pickups
- Possibly other chassis bracing
- GT headlight lifts or remove lights completely
- Repaint car (TBD how extensively)
- RSR finish Fuchs 16x8's up front, 9's in rear
- New graphics/decals


One upcoming decision is whether to keep the sail vinyl or go body color without vinyl. I've always liked the factory vinyl and bright trim look but could go either way on this.

The work could start as soon as Tuesday and I'll post updates and pics as I get them. This is not going to be a CW rotisserie sort of project since it's a race car, so progress should happen quickly and I plan to run the POC Laguna Seca event towards the end of August.

Cheers,

In my race car building days I was obsessed with several things among which were low over all weight, low unsprung weight, & low CG of the whole car.
I jumped through a lot of hoops to get there without screwing up the the camber, toe curves....& bumpsteer, of course from the stock settings......I ain't smart enough to re-engineer the suspension to a better point than Porsche did. Due to some professional help with shock valving (& shitcanning the rubber bushings) & some fairly radical stiffening of the chassis (lots of room for improvement there) I feel I was reasonably successful. Any advice I offer is based on those obsessions plus the absolute need to have fairly compliant suspension to handle the bumps of several AX venues.

Reading your post, Chris, would lead me to believe your car is no longer going to be street legal (no headlights?). Your need for DOT legal rubber confuses me. Are you running some kinda spec series rubber that calls for some oddball wear rating? Hoosier makes DOT legal R&A6s and the available rubber is as good (better IMO) in 15 inch as 16 inch.

BTW, tscrihfield, *lowering* ones spindles is counter productive and would not effect wheel size. (IMG:style_emoticons/default/biggrin.gif) Terminology counts.

I guess the proper way to say it is "raising" the spindles to drop the car... (IMG:style_emoticons/default/dry.gif) You got me on that one! I was a little tired when I posted last night...

But I honestly can't because I tried to install my 16" wheels and they hit the lower control arm due to spindle location. My 17" wheels have room but the 16s are a little too small...
