V1 Chris’s 2007 SS/SC track frame build for autocross

[ccannx]

Got a cardboard template for the spoiler and rear engine cover welded up to support the spoiler. After its all mounted up I will need to pull the springs and mount the rear fenders to trim whats in the way for wheel clearance.

This will meet E- Mod rules?

Got the Bikini top from Jbintx yesterday and tightened it down. I corded it a little differently side to side than front to back because it was putting a lot of stress on the eyelets. Super happy with it tight as a drum and will keep the sun off me.

"Roof" option

Hey all just wanted to let you know I'm working on a roof of sorts for the Goblin. I've reached out to a company that makes replacement canvas tops for off shore boats. After a little back and forth I created a template using a tarp. I've sent them the template and I'm waiting on the top...

Looks great. I would have 100% hit up JB for one of these if I had a track frame. Community skills, on display once again!

 

[JBINTX]

Chris: The color paracord pops! Good choice.
Hopefully the top adds to aerodynamics and shaves a few thousandths off your next track day....

 

[ccannx]

Re- made my "test fit" front steering arms for just a little quicker steering and connected them with rod ends.

Old vs new.

Looks good! How far out do you have the hole at this point? I put mine about 1/4" further out than the DF ones to slow the steering down but without being able to test it right now I'm not sure that I'm going to like that.

 

[ccannx]

Checking the toe after swapping arms out. Toe doesn't change loaded or unloaded.

 

[ccannx]

The spoiler is because of the SCCA no wing rule for autocross class?
Looks like the cover would be effective at (mostly) sealing off the engine compartment. Can I ask why the air filter is partially through the cover?

Yes no wings AFAIK in E-mod. I don't have space for intake pipe behind the strut so I'm sticking with the pipe that comes with Zzp's turbo swap. Should be plenty of air in that high pressure zone in front of the air dam.

About 1 inch hole to hole currently but these will allow me to go back about 21 mm to about 1/4 away to keep the stock steer ratio and delete the Ackerman. Hope this helps.

 

[Fozda]

I moved the holes outward to reduce the Ackerman, I just hope I didn't move them too far rearward causing the steering to be sluggish or anything.

 

[ccannx]

You will have to get it to an event and see, once you get it close you should be able to fine tune with toe -+. Toe out will speed up turn in and toe in will slow it down. I guess toe is to ackerman what camber is to caster.

 

[ccannx]

Spoiler is mostly done. Now I need side panels to replace my plastic sheets.

 

[ccannx]

Dropped by the local metal depot. They had some scrap steel diamond plate in the scratch and dent section. Picked it up for 40$. Big enough to cover all the way from the front firewall to midway below the seats. Finished the last bit with some scrap metal.

 

[ccannx]

Made some permanent panels for the sides. The fronts are steel(so my magnetic numbers stick)and rears are carbon fiber.

 

[ccannx]

Brake proportioning valve installed on front brake lines.

Brake proportioning valve installed on front brake lines.

You will notice a big difference. Post a report for us after your next few hot laps with it.

 

[Rttoys]

Yep. One of the best mods you can do. Much better brake pedal feel and control.

 

[ccannx]

I will start with it fully open. The brake feel is pretty good to me stock but want to direct a little more bias towards the rear.

 

[Rttoys]

Mine has about 10 1/2 rotations (looks to be the same brand as yours). I started at full open and ended up at about 7 turns open. After I still locked up the fronts once at Autocross last weekend, I’ll probably go 1 more turn out and see how that feels. It’s all going to depend on how you like it.
