Figured the forums would like to see this. All work done by JRD Tuning, located in Atlanta, GA. They are building a WRC Spec Evo 9 for a customer. Genuine wing(molded in house), custom subframes, long wrc travel, etc. All of the cad work was done by hand from Johan Ragnarsson (owner of JRD).

JRD has run my Open Class Evo 9 for the past few rally seasons. You can look at my FB page for detailed pics of my car and some more of their custom work. Lots more pics of this WRC car when it is finished, but here are some right now. Sorry, no upclose of subframes, arms, etc, it is all custom by JRD to remain private. JRD is part of the Panoz group and has experience in all forms of motorsport





Suspension cycle mock up. 12 inches of travel... yes that says 12






Front End with quick release, incase of hard landings


Front end separated


Interior:








WRC Wing made in house


Body Panels being mocked up


Super Widebody rear(cant tell because the track of the car is much wider as well)


Jack Stands


All done by hand, measured with CMM









Paint is on










Motec Dash to be added

These guys can make whatever you need for your track car. Get in touch with them for any projects

 

Nice Joseph! Thanks for sharing. I drive past them everyday now that I'm at a race shop near Road Atlanta. I'd love to check out the facility, are they hiring lol.

 

what axles you going to use with all that travel? build looks crazy high level

 

Custom axles. Custom uprights, but the oem hubs bolt on to the uprights

 

If this is for open-class WRC, then I assume that the above shows a front-default Haldex-type center. If my assumption is correct, can you say some more about it?

 

It is for rally america open class.... But wrc design inputs. The picture you quoted was mid cad design. The final transfer case cad is also posted. It will be using standard casing with ralliart internals for ACD

 

For open class in RA, you can run a Haldex, if you wish. L'Estage does not. Nor does Higgins. But rumor has it, Block does (since he's addicted to the hand-brake). Do you have $30k laying around? tee hee

Or, here's a crazy thought. If the ACD is attached to the center in the same way that the VC was attached to the center of a DSM, then it connects the input to the rear output. Therefore, you could weld the center into a spool, strip the connection to the rear, and use the ACD as the hydraulic coupling to produce, in effect, a front-default Haldex. Yeah, OK; that's crazy. But it's something that I've been playing with on napkins.

edit: I should have said this in my first post in your thread: nice car

 

One question about the front shocks, if you don't mind. I know that one reason for having the shock come across the top of the axle is to have the room for more travel without giving up caster. But I'm curious if this design also creates anti-dive (during braking) due to the torque on knuckle from the brakes. Napkin geometry says that it would, but I couldn't get verification. It would also explain why left-foot braking is more effective with this design.

 

entering in to national?

 

Purpose of question?

I'm sure it will do all forms of events including NASA & USRC

 

Just a thought but you might have them do the cage :-)

Also ask them about the ACD, tuning it and what rear LSD to go with on tarmac if using a tuned ACD

 

Wow. I'm a pinhead. I hadn't clicked the FB link before now (because FB is evil) and the front-to-back name for your account slipped past me. Silly me.

 

Joe, that is great. thanks for posting up.

Would u mind letting me know who does your ACD tuning and also what type of LSD are being used front and rear?

Thanks very much

 

because there's a big difference between regional and national. And that's looking like a national level car to me

 

Agree on the car spec part. But for the drivers who just want stage miles/fun, rallies are rallies, club or national doesnt really matter at that point
