Great picture. Car looks and sounds better than ever! Thanks for the hospitality and the hook up with Chet, I'm pretty sure I had a good day.

If you've got video of the last session with the Panoz and Porsche I'd love to see it from your view, that was some good racing!

:thumbsup:

Greg, is the rear window in the mustang lexan? In the photo above, it looks like the top of the window is pulling down? Could be just an illusion...
Car looks great, and I'm glad you chose to work with Ron. Enjoy!

Yes it is a R model rear window.

Rob is correct. They are a composite leaf spring I had made in a specific spring rate for this package.

The advantages are significantly lighter weight & less harmonics. But I only recommend them if you're running a panhard bar or watts link with them, like we were here, so they don't see much twisting forces.

Hi Craig!

Greg,

I doubt Ron and his guys would have missed this, but I had to trim a bunch off of my outer shock outer tower braces / factory bump stop mounts for tire clearance when I went to that much backspace (I know a lot of mustang guys that just remove them when they go to coil overs). Depending on your camber gain and travel, it looks like the tire could get into it at full bump.

The car looks great by the way. I really like those wheels.

This is how mine turned out:

They still rubbed during autoX runs even after I took a cut on them.

-Craig

We removed the factory bump stops. No rubbing.

:cheers:

Thanks Charlie!

The only thing I tuned on Saturday was tire pressure & brake bias. The car was neutral off the trailer. We'll dial some more grip in the front or rear when we find the limits.

While we weren't at the limits in these first sessions, it was fun to see Greg passing many of the cars & drivers that were previously faster than him.

:cheers:

I loaded up from there. Pretty sure he was running the Lotus today.

Hey G!

It was fun hanging with you Saturday. Camaro looked good on track.

Greg told me his goal was to have the Mustang feel 25% like the Lotus & we achieved 75% ... which was fun to hear. Of course I would have gladly drove back to Sac, got parts & fixed the pinion seal problem, but he'd only get a session or two. So Greg made the call to do it later & drove the Lotus Sunday.

Hey Greg, it was a fun project & a rewarding track day. Thanks for the opportunity to make your car handle, steer & brake better.

The Mustang is like a completely different animal now... totally neutral handling - and just had so much grip... and best yet - didn't do anything weird.
This is a combination of a balanced high travel/low roll suspension strategy combined with zero stiction & secret sauce JRI shocks.

The motor is more powerful FEELING. It also just flat sounds better. The brakes give great feel and were very effective.
Now you have some real brakes you can be confident in when driving in deep.

All in all.... WONDERFUL.
SWEET !

The pinion seal issue was unforeseen and really not fixable at the track -- so I said "that's why I have a back up car!".... We'll fix this later as it's a very minor deal.

I can't tell you guys how impressed I am with what Ron has been able to do with the old girl. It's not just the parts.... it's how they all work together. I can't say "this" was better or "that" made a difference. The cars running gear is all new... and it ALL made a difference. Where I used to lift and roll thru turns 7 and 8 --- I'm now taking WOT.... that's just HUGE! The off camber turn 3 is just no biggie now -- where I was always just waiting for the ass to step out.... My confidence level and fun factor just went up by 100 fold. Amazing. What a great weekend!

Like we discussed after your first hard run, the new low roll angle suspension set-up not only has a ton more gripacity (a new made up word ... LOL) & cornering speed ... it's not "edgy" like the old high roll angle set-up was ... and you can run any line with it now.
