How do you best configure a six-point rollcage in a Superformance model GT40? It seems best to place the rear most roll bar in the engine compartment, away from the driver's head, in order to increase head room in what is already a cramped cockpit. (Two vertical bars would then punch...

I'm not sure if this is endemic to all SPF GT40's, but my accelerator pedal is very stiff. It really becomes an issue during heal-and-toe downshifting. A friend looked at it and feels it's due to the design and not the spring. Whatever it is, I'd love to find a way to lessen the tension...

What was the material used on the original GT40 racing seats? It looks like some sort of simple, black parachute nylon or the like. Does anyone know the name of the material and a possible source? Also, were any of the seat grommets in the original cars in a brass finish? Or were they...

I recently took P/2192 to Sebring International Raceway during a NASA track day (HPDE) event. Some of you will recall from a previous post that it was here that my engine ate the distributor about halfway through the weekend, so we had very limited runs. Also, we were having issues with what...

I could use some of the high-powered expertise from fellow members on the board to help diagnose a problem that led to my engine failing this weekend at a high performance driver's event at Sebring. The engine is a Keith Craft 427w with an all-aluminum block and TWM fuel injection with FAST...

While the OEM exhaust is quite adequate, I had always intended to install strait pipe megaphone exhaust tips on P/2192. My hope was that they would make the car sound great, but not so obnoxious that I'd wake the neighbors or agitate law enforcement. I also like the look of large, agressive...

Here is the solution my brother Alan came up with when faced with finding a permanent mount for a Valentine One radar detector in P/2192. I wanted the detector fixed with optimum 'vision' forward and to the rear; at the same time, I wanted all of the controls to be near the dash and all lights...

I'm preparing to replace the SPF original rear view mirror with an authentic Lucas 608 model I picked up in the UK. Has anyone had experience in removing the factory mirror from the windshield? I've had a couple of people tell me that there is the possibility of cracking the windshield when...

We're in the rainy season here in Florida and in heavy rain, water continues to be a problem for SPF P/2192. I've begun plugging holes and gaps in various places but it also appears that water is entering through the NACA ducts on the hood forward of the passenger and driver. For example...

I've now had P/2192 for a few weeks, hardly enough time for a comprehensive report, but nevertheless some things have become manifest. The following are a few initial thoughts on SPF ownership. Bear in mind, these are my experiences and opinions: Yours may be very different. Dealer...

Well guys, after a one-and-a-half year wait I took delivery of P/2192 on Thursday and, along with my brother, drove it from Olthoff Racing in Charlotte, NC to south Florida – about 1,100 miles. Great trip! This is the car that Car & Driver tested about three weeks ago and is slated for a...

Some of you may have heard that Dennis Olthoff delivered my Superformance Mk. I to Car & Driver magazine for a road test. Olthoff Racing did a superb job preparing the car – fantastic attention to detail, in keeping with their reputation. [For background, they installed my Keith Craft...

It is rumored – rumored mind you – that my car may be ready next week, whereupon I will be driving it south to Florida with jubilant abandon. In the event that I do actually obtain custody of my Mk.I, I was wondering if there might be some other Superformance owners around Ft. Lauderdale...

Can anyone explain to me how, back in the day, they coded engine serial numbers for the GT40 Mk I? I'm creating a data plate for the engine compartment and would like to replicate something that will approximate the naming protocol used by FAV or JW Automotive. Thanks, guys! Kim

Does anyone have a photo of a scrutineer's tech sticker from the window of a mid-60's GT40 competing at the Le Mans 24 hour race? Any other similar tech stickers from that era would also be greatly appreciated! Thanks, Kim

As I sit on my hands, waiting to see if this will really be the month when I take delivery of P/2192, I started wondering: Assuming a right-hand steering car, what are the tell-tales that would distinguish a Superformance Mk I from an original car? Specifically, when viewed from the outside...

Has anyone successfully replaced the standard fog light/turn signal array located under the headlights with the larger, round driving lights found on several of the Mk I cars (e.g., P/1076)? I thought I had read somewhere that one of our colleagues had located these driving lights with built-in...

Does anyone have experience in registering a GT40 in South Carolina? My Superformance MK I will be ready soon, and I've heard conflicting stories; for example, I was told that SC was one of the few states that allowed short VIN numbers. Obviously that would be neat to have GT40P/2074 as...

Well, I'm within a month of receiving my SPF Mk I from Olthoff Racing, after waiting almost a year for a transmission. Dennis & Co. have been great, and are as much hostage to the ZF shortage as anyone else. (Hopefully a reliable source will come from Quaife and their ZFQ, but that remains to...

I recently did business with a firm called Anglo American Racing in Arizona. They came highly recommended, and doing business with Martin, the proprietor was pure delight -- a great guy. I ordered several items, and received most of them except for the shoes, about $200. When I called to...
