Rear scoops worked awesome. Time for a re-work to make them lighter and better looking. Still looking for a rear fender solution before I give it an honest paint job.

Where did you find that cool large muffler? Did it cut down your noise levels better than the RB universal muffler?

That's a RB 3" universal. It does a good job. Soon it will flow into a second RB 3" Universal.

It was wet out and I dove into the corner like it was dry. Locked the rears up under braking and she snapped out. Not enough time to catch it so off we went. The left rear caught soft dirt and sent me into barrel roll ending on some large rocks.

The car is, surprisingly, relatively unscathed. I knew I was overbuilding the safety gear, but this proves it.






The hood closes fine, we just had it open to run chains to the frame to yank me out of the woods. She fired right up with no leaks and we started going up the road to turn around before two of the tires decided they didn't want to play along.

The damage tally:



Unsure I'll be buying another set up these given the way that heim failed.



That's all I can see right now. I'll be pulling the suspension apart even further to check for more damage.

I think I'll make my own toe links this time. I really don't like the way that heim joint failed on the Battle Versions.

Make 2 sets of tie rods.. I'll buy a set from you. That is the last stock piece on my suspension.

How willing are you to drill out the tapers in the stock toe arm mount positions? I'd rather use a larger heim and bolt than the tapers allow.

I'm looking at Aurora heims with a static load strength of 23,310lbs. Three times the rating of what was on it. Lower breakaway force as well, so it won't effect movement rates as much. They're not cheap, around $95 each heim.

I'm willing. That will be a fun job.

That said, how hard did you hit? I would rather the toe link break than destroying the trailing arm, subframe and unibody if I take a hard lateral hit

Just sayin!

I'm building for tarmac rally, so I overbuild suspension whenever I can. The heim failure could have been what sent me off. No bueno.

Time for some 50mm motorsport bilsteins

my AWR toe links are based on 3/8" heims with drilled out tapers (to 5/8") and bearing spacers. I assume you're planning on 1/2" hiem joints?

make sure you get the heim joint height back in the same spot or you might get some weird bump steer in the back.

Anze suspension is putting a Penske setup together for me.

Looking at 1/2" Aurora heims. Good call on the height.

While the Hillclimb car is down, the LeMons RX7 made it's debut.



Good prep meant all we had to do when we got to the track was sticker it up. We had some fun.










We had zero mechanical issues, though 3rd gear was getting a little crunchy on day 2. We finished with 635 miles of racing on the clock and it drove itself onto the trailer. Pretty pleased overall.

In additional rotary-powered news, the 73 Super Beetle with a REPU heart is nearly ready to hit the road.

I thought so too, but it doesn't seem to be an issue after idling for an hour. Being in the open air certainly seems to help.

We decided it was a bit loud still, so Jeff bought a Supertrap weld-on unit and I got busy with the metal glue gun.




Running all the plates it still seems to have cut about 6db off the most painful end of the rev counter. I'll call that a win.

In other news, the Hillclimb car will be getting a turbo this offseason in the name of DB levels and packaging. More power will be a side effect.

Goal is 300whp, which should be really easy. Stay tuned for custom manifold building and turbo selection, as well as to tell me I'm wrong with my choices!


****'s about to get real wirey with the EFI conversion too.
