.001 - .0015 preload is more than enough. The side loading capacity (axial) of deep groove bearings is only a fraction of their radial capacity, so the load on the balls from the preload is additive...

Run a thermostat.

Things never break back in the shop - they wait until the start of qualifying.


You rarely break anything that you have as a spare in the trailer.

Steering boxes and racks will ALWAYS wear the most where they are used the most - in the straight-ahead position.

Running the FC front tire on a 5.5" rim will most likely necessitate upping the front spring rate to keep the rate at the contact patch the same - mounting on the narrower rim will decrease the tire...

I still have the original March parts drawings for that box and for the f & r uprights.

Which is exactly what my last sentence implies. :)

Yea - the homologation "inspection" always, in my experience, was just a paperwork process. The only full tech inspections I ever saw were after crashes (roll bar thickness), and the very first...

Actually, supplemental heating of the tires is indeed allowed ( 6.1.1 Tire Temperature Management), but must cease 30 minutes before the first car of a run group starts his run. Of course, that can...

There is plenty of info in the GCR about the homologation process that you can look up. Read 9.2.2 A quick read of all of the logbook requirements (9.2.1) is a bit confusing, so I'd have to spend a...

If I were to suggest a rule improvement for CM, I would get tire warmers and blankets on tires in between runs banned. While it won't totally cure the performance handicap a single driver car has...

"Chassis Plates" are not required in FF, nor part of the homologation requirements - in fact, the FF/FC requirements only state that homologation MAY be required, with the need of referencing 9.2.2...

You misunderstand homologation.

The only things homologation are concerned about are the general construction per GCR requirements for that class - tube frame per the GCR - the fuel cell and...

Looks like these may be DG dogs. They are 2.352 ID.

Looks like these are DG232 then, as they are .500 across the dogs. Anyone who wants them, call. 317-273-0089. $75 each.

Correction - all...

Just found a can full of old dogs rings that I think are FT/FG - 2 new and 8 used. Anyone have one that they can measure tho OD for me so that I can verify these?

Grinding or turning the pistons will be the easiest - You just grab them by the ID on an expansion collet and turn at a very fine feed rate.

Reboring the bores would be a real PITA - you would...

Do the CM rules allow the wider FC wheels?

Just wait to hear the wailing if the states and the feds start taxing road usage fees and sales taxes for EV charging.

You can also have them plasma sprayed and turned (or ground) back to the correct dimension. You may need to have them turned slightly undersized first.

Try posting a picture - it works wonders in identifying things.

Yea - the 2 million $$ I sent you for that Ferrari Dino that you advertised in Esquire Magazine..... :D:D:D

Of course it can, since that is what it came out of in the first place. The problem is that it cannot be used with any of the Hewland parts, since they are all very different.

Do it! While it will take some work to get the car in proper condition, it is one of the best classes to get started in, as the car will not be so fast as to scare you right away, and the competition...

Steve may have more details, but to me, the bellcranks look like Citation, but the trailing links are like none that I ever saw come out of our shop.

Tow hooks would only add to the potential for car damage - too many tow truck drivers hook up very out of line with the car, and then try to yank the car quickly, especially if it is stuck in mud....

The car was backwards and sideways before the strap yanked on the roll bar - not that easy to see from the video, but after a few times of watching it slowed down, it becomes obvious that something...

No idea what the rules are about this - if any at all - but my advice to a driver would be to get out of the car if the tow driver used a solid connection, and then undo it.

Whomever that tow truck driver is, he needs to be educated on how to properly attach to a car, and how to tow, as he obviously doesn't know either worth a sh!t.

Also looks like it was hard strapped, which should never happen. The driver should have refused the tow once he saw that it was going to be a non-detachable strap attachment.

Further, is there a...

Sounds like a lawsuit in the making.

Knowing Roger, however, he might just pay for the damage himself.

The halo is nothing more than a mostly horizontal tube the runs from one side of the car ( upper side tube) forward and then curves up and over the drivers wrists to the other side. Steve added it in...

Just turn the droop limiter ends down a bit until they clear. Each time that it hits the spring, you will lose some rear grip - maybe not enough to really notice, but the loss is still real.

I made a broach for the stock VW box splines about 30 years ago. It is .564 od x 36 splines, if I counted them correctly.

How is the supply/demand for front spindles. I can set up and do these again (need to find a new steel foundry, unfortunately), but have no idea what the price will be - I can guarantee that the...

Tried to reply to your message, but your box is full!

Just put a T fitting in the clutch line somewhere, along with a length of hose that can be capped off after bleeding everything. Once the engine is running and the car in gear, pull the cap off of...

Definitely not a mechanical issue ( broken diff, slipping splines, etc). It is related to heat, and most likely the expansion of the clutch fluid is causing the clutch to partially disengage.

If I remember correctly, the Jim Russell school cars back in '80-81 were all '78 VDs with the side radiators ( but no sidepods).

Rather than all this nonsense about changing car specs for either class - FA and F1000 - how about something simple that costs no one anything, can be implemented in a heartbeat, and would give the...

So sad to see what has happened to that great class.
