Just returned from the CSRG race at Sears Point. Thought some might be interested to learn that I broke a front stub axle. Wheel fell off on the cool-down lap. No damage to driver but some body dama
I too lost a wheel at Sears Point last weekend and would like to share the experience with anyone who is racing on knock-off hubs. My 1964 MGB has the early fine threaded knock-off hubs and caps. I
I've seen this before. Not common - but it can happen. I check the hubs on my 3000 after every event (dye penetrant). Denis Welch in the UK has some stronger front hubs that I would seriously look in
Two points: whenever you experience a failure of this sort, please report it to Ely Fishkin, the Secretary of Vintage Motorsports Council. He is valiantly trying to create & maintain a database of v
It's difficult to argue with someone who's technically right, but let's get real. Of Course it would be good to have all vintage race cars suspensions magnafluxed yearly. I can think of a 100 other s
The problem with Magnafluxing is that it only tells you that the part's not cracked *now*. If it's past it's fatigue life, or installed wrong, or being over-stressed (like big sticky tires on suspens
Here's my 2 cents on this one: While annual magnafluxing is good advice, I think most people only do it when they have to dissassemble and/or rebuild something. Taking your suspension completely apar
When you talk about buying new parts I recall a friend in the early 50's building a Ford flathead V8. He bought bought five new sets of connecting rods and had them magnafluxed before he found eight
With all due respect, I just have to disagree ... yes there are probably 100 other safety items that one could do, and I understand there is a point of marginal benefit and we don't need go as far a
Mark, I've raced vintage for almost 20 years, I've done as many as 15 races in one year. I've raced all over the country and I can tell you that suspension failure problems are extremely rare. This i
I could be wrong but I heard that the reason that Yoko-- A008R tires were outlawed in certain East coast race groups was because the early suspensions could not take the strain, and , of course, so t
You bring up a good point. The typical 1950's or even '60's production car was not designed with today's tires in mind. Even my relatively skinny L-series Dunlops undoubtedly have more grip than was
In the TR-4 Competition Preparation Manual, Kastner recommends magnafluxing critical suspension parts every four races. I'd be interested to know how often people do disassemble, inspect and rebuild
I doubt that any asphalt race track is as bumpy as an English country lane. ;=) They were designed to take a beating, but this is one of the reasons I like being forced to run the hard-compound Dunlo
If you want to see the aftermath of using sticky modern tires on a vintage suspension, even after reinforcement for a known weakness, see http://world.std.com/~jeh/racing/sprint59.htm . Only took two
