Several flash lights and spare batteries. Cell phone car charger!

it's a start...

Another Pozzi original based on the factory design.

How heavy is your trailer going to be?
just wondering if you are pulling strictly from the bumper?

Never thought I'd say it but that's not bad. :unibrow:

it's just the start - it will be triangulated at the bottom as well and will be welded.
All told the trailer - loaded - will probably wind up being around 500 pounds - should be about 25 pounds on the tongue.

How about a tap and die set and spray can of cutting oil.
Spare fuses, wire and splices for electrical issues

Cool.. you know how some of our readers LOVE Camaros with trailer hitches.. lol

The good news is, I only had to drill two holes in the lower pan to get it on. With some black paint on it I hope it will not be so visible. This was fairly quick and easy and should be plenty strong enough for the weight we will tow. If I had more time, I'd make a square tube plug in version that could be left on the car, but this only requires 4 bolts and comes off easy. I need to start on the front hubs soon.

ZR1 Hubs
 

David

What is involved in switching to the ZR1 hubs? How are they different than standard C6 hubs, and what do you gain -- stronger I assume. Will they alter any of the front geometry (scrub radius, etc)? Thanks.

Pappy

The SKF hubs are a direct replacement and bolt in exactly the same was as the standard ones. As far as benefits...

ZR1 Hubs
 

James,

Thanks. I see Zip Products sells the hubs -- do you have another supplier?

Pappy

I bought mine from the guys at the Waterford Hills Road Race Course (Direct Motorsports). I tried ordering from "the big guys" who offer these and was given the run around for three weeks - they were on their way, they were missing wheel studs, they were backordered for a month - before i had to cancel my order (horrible customer service). Finally, after seacrching for a day I found these guys who had the hubs drop shipped from SKF the same day. Incredible customer service and cheaper to boot.

This is what I run.. I will second that they are direct bolt in deals.. MUCH stronger and stiffer and can better handle side loading from high-g turns. Where regular hubs might last a few races these tend to last a full race season or longer.

They will noT change any front geometry. Oh when you switch hubs you need new GM TTY bolts.

David finished up the hitch today - welded, painted, and ready to go:

Trailer should be back from the paint shop on Wednesday.

Sorry for the small hijack, but how do they change the geometry? and why TTY bolts? Where can I get them? I purchased my ZR1 bearings from Pfadt.

Thanks

I was over at the Pozzi's yesterday James,Dave did a real good job on the hitch.He was joking the whole time how he usually over-builds things,with this hitch for that little trailer,he had to remember to KISS.;)

Wrap looked real nice too...:unibrow:

They only change the geometry when you're tired and type a "W" instead of a "T" :rofl:

Seriously.. of all the places for a typo.. Shows there is a God with a sense of humor.

They will NOT change the geometry.. In fact they will help keep the geometry stable by resisting flex better.

Nice! Congrats. Shiny Side up :thumbsup:

Got the new studs for the front hubs today, metric this time, 1/2" wouldn't fit.

Yesterday I picked up the freshly painted trailer, finished/tested the wiring in the trailer plug, it's inside the trunk and we'll just close the lid on the pigtail, it's a flat strip of 4 wires so it shouldn't get damaged. Need to tape things up and finish it today.

Got the rear axle bearings sealed better, a few drops of oil were seeping past the O ring seals on the bearing OD.

Sweet trailer:D Should get that wrapped as well?

Agreed the trailer turned out well are you only going to be able to drive 65 between stops.....:_paranoid

I am really amazed at how well the trailer cleaned up; it would be cool to wrap it but time and $ isn't on side for that. Instead we're going to decal it up some (Dave - find a way to get me some Source stuff before I leave) and have some fun with it.

I have to admit that I don't know all of the speed limits along the route but we're not overly worried about it. Talking to Mark last year he said that there were two schools of thought - 'steady speed limit driving' with decent mileage and 'slightly exceeding the speed limit here and there driving' with increased gas stops. Neither seemed to have a significant advantage. I think that if we can cruise at 75 more often then not that we will be happy.

I think he meant "Is the trailer capable of going over 65mph?"

If you need more stickers.. just let me know :)

And remember.. take GOOD photos and good journal notes.. don't be afraid to ask someone to snap a pic so you and Dave are in the shot.

The trailer and hitch turned out nice. It will be nice to have a little storage for the trip.

Good luck with it.

The trailer should be up to the task - we hope.

If you have an opportunity send some to David - dark colors. We'll keep you hooked up.:yes:

You got it! Should be lots of camera's around for the week, we'll try to make you proud...

Thanks Mike. Hopefully it allows us some breathing room in the car, without it I think one of us was going to have to carry the front spare on our lap between events. The other nice thing is that it will allow us to carry a couple of jugs of fuel - a little extra breathing room will be appreciated.

What a difference some fresh paint and a tune up makes...

http://www.onelapcamaro.com/2010/trailer%20new.JPG

David will fill it up tomorrow and see how much room our spares and tools up. Then... the moment of truth... the test drive!

but as time gets tight - the car hits the highway Saturday - small things are sure to crop up. Lesson learned - the new hubs aren't a direct replacement for the stockers in the ATS spindles. ATS had altered the hubs to use a stud with a nut on it and the material thickness of the SKF hubs is slightly different and the swap isn'r as straight forward as you would hope...

http://www.onelapcamaro.com/2010/hub%201.jpg

David took a shot at increasing the clearance but there are still issues...

http://www.onelapcamaro.com/2010/hub%202.jpg

...so we'll have to set these aside for now and change them out after the race. I've got a spare set of ATS spindles in the garage so I'll pop a hub out and we'll bring it with us as a spare instead.

Sorry to hear you're still having problems with those spindles guys,but that trailer really turned out nice Dave,night & day from when I saw it...:wow:

Best of luck to you guys...:yes:

Trailer looks great. Best of luck and we all will be pullin for you guy's.

The good news is that the old hubs are in good shape and, in all honesty, shouldn't be a problem unless we make them an issue. I'll pop one out and we'll have a spare if we need it - just in case.

Hopefully we have the balance of our spares in tomorrow... Kinsler has sent us a fuel pump which arrived today, as did another set of tires and (thankfully) our shock. AWESOME customer service from Penske!

Tomorrow we're expecting our Raybestos R43 pads which we'll carry as backups (on the other side of the customer service fence are the AP reps in California - after a month and a half of email and phone messages I wound up calling England to get help. As soon as the OLoA is over I think that there will be a change coming there) and some more bits and pieces.

Currie Enterprises also sent us a care package....

I had forgotten that Tyler had modded the hubs for the spindles sorry for the luck but everyhting else is looking great. Cant wait to see some action shots really pulling for you guys:woot:

James,

What is the gear ratio on your new rearend? 3.89?

Also, is your magnum the .63 final gear one?

Thanks

I can answer this since our cars are vitural clones.. lol

Yes to both of those questions.. it makes a sixth gear that is actually usable and doesn't make the car bog down at typical freeway speeds.

When you say "useable" based on your specs (26 inch tire, .63 final gear, and 3.89 rear end) you are doing around 2500 rpm @80 mph. Wouldn't it be nicer if it was closer to 2000 rpm @80 mph?

For example, I think Jackass has specs like this:
(26.6 inch tire, .50 final gear, and 3.90 rear end= 1971 rpm @80 mph)

Let me know if my figures are off...

Thanks and sorry for the small hijack...

What he said - lol

I will probably change out the gear ratio in the spare 3rd Member after the One lap to something around 3.55 ratio (give or take) for the Silver State. Eventually we want to get in to the 150+ class and a drop would be nice for that.

Excellent customer service (by the way) from Currie. We spoke to them last week and told them what we were looking for and had the 3rd member assembled and shipped out the same day. It's essentially the same as what we are running now (they rebuilt our old one last summer) - Strange aluminum housing, True-Track differential, 3.89 gears and heavy duty pinion support and yoke. Great products, great price and fast!

My personal preference is to have some more RPM vs less. I know that it's not perfect for mileage but I'm trying to balance street and track manners and I just hate borderline lugging in 6th.

But... in all honesty... the only time I've ever been in 6th I've been at 110+

I guess.. if this were my daily commuter, but I don't like my car all quiet and luggy.. When I had my T56 (.50 sixth) I never drove in 6th because it was too quiet. lol

I probably should swap to 3.70 gears given how much torque my new engine has, might make 1st gear more friendly. The hard part is that my gears are expensive (lightened and polished) so it's tough to toss them to buy new ones.
