Ben, is that actually a bushing that goes inside the rod end, or is that washer at the end of a single shear setup like a balljoint (it looks like the latter to me).

I will reiterate that I think a 7' wide is a huge advantage and worth sticking with. With a formula car, you can easily walk beside the car, no issue. With a sports racer like mine, it's harder,...
This question is asked often and it's worth reading through the towing forum on here for more information. You will need a 7' wide trailer, no question, for your car to fit through the door - and...
I cannot overstate enough that there are "race ready" cars that will take $5k to make safe and legal, and "race ready" cars that will take $25k to make safe and legal. An experienced eye that knows...
Some of these photos are a little older, but still provide some general idea. Removing the rear wing assembly is also only 4 easily accessible bolts and I have given some thought to doing so which...
I have towed my Stohr WF1 in my 7x18 enclosed aluminum EZ Hauler for 4 years now. The door opening is 76" wide on mine, the cables on the rear ramp are 73" apart (though could be relocated if...
To be clear, that might as well be a Stohr. That's a gen 1 car, the car that Stohr built before the WF1, which the "West" version of is identical to a Stohr. The difference in performance between a...
Your friend's car would be nearly $85,000usd landed in the US - you can buy two P2 Stohrs for that and still have some money left over. /rolleyes to "woe is the expensive Stohr being allowed but...
It seems like a lot of the higher end classes are doing fewer if any local races but a fair number will show for big marquee events such as June Sprints.
I suppose it makes a little sense to me as...
Taking the same tire you are already running, and moving from a 5.5 to 6.0" rim is not going to require a 200lb-in spring change, sorry, there's no way that's correct. I would venture a guess that...
No real dog in the fight, but I think it makes sense to allow 6" fronts if 8" rears will be allowed.
It allows you to sell a complete set of 5.5" FF wheels and buy a complete set of 6/8" FC...
If you were ordering a brand new Stohr, the cost of a P1 car is not that much more than a P2 car since all the big tickets for the car - chassis, bodywork, etc are all identical - basically the...
I have run the C92 on my 1025lb with driver Stohr along with the Pirelli purple ultrasoft and yellow "soft race compound"
The C92 is nowhere near as soft and I don't think will work well for your...
I think a better question is what will you do for header, airbox, oil pan (dry sump? wet sump?), mounts? These aren't trivial tasks for a motor conversion so you might find it to be an easier road...
At the onset, I don't think that Pru's recommendation that a harder tire be enough of a handicap for an FC in CM is accurate. The amount of handicap the hard tire provides would be highly variable...
This is backwards, tire blankets will help single driver cars more than dual-driven ones, given that there is twice as much time between the car running on course compared to a dual driven car.
...
What's the rationale here? Add formula continentals which are faster cars, but handicap them with slower tires, and hope that is approximately the right amount to equalize them?

There is nothing to be gained by being argumentative here.
The simple, and only official, way to take this forward is to request an answer via a letter from the CRB:

A ton has changed in BoP between 2020 and now. The reality is that the current crop of DP02s are almost a new car at this point - Zebulon/HRP have designed new floors, complete bodies, front...
Not currently - that is the point of this thread, to gauge interest and garner support I imagine.

Hoosier, Pirelli, Avon, and Goodyear all make 13" FA sized tires.
However, if your idea is to increase the PFM's rear tire from a 13x11 to a 13x14, I think this is a misguided activity. That...
I sent you a message on Facebook as we are both in Vancouver, but in my opinion, there is not one that is definitively better, but rather pros and cons to each.
The dry sump can potentially make...
They are extremely basic, by design in terms of suspension. They also are very small physically so the question of whether they are actually 1) large enough and 2) strong enough for your application...
As always, David has the goods! The only thing it looks like you need is a 40.5mm restrictor and you're good to go at 1300lbs with driver.

Your car is undoubtedly legal for P1. If your motor is a stock gen 1 Hayabusa 1300cc, it can be legal for P2, but the car will need some changes:
1) rear diffuser will need to be partially blocked...
For what it's worth, if you look at the results from 2021, you will see James French (4th) is running exactly that - a Swift 014 Atlantic with sports racer bodywork. And the DP02s that are generally...
Love the enthusiasm. Now for the reality check: for the price of selling your WSR, plus not buying an Atlantic motor ($10k), transaxle ($7.5k), and floor ($5k) - you could have a WF1. It will have...
If the car is ~$70k with a modern 4 cyl dry sump engine, pneumatic paddle shifting, data, ready to race that's great value IMO.

The idea that 22 people have signed up to buy a new car which has no information and 0 chance of a competitive landing spot in SCCA seems downright implausible. "Will run with the rest of FA" is a...
I would think if the goal is not to cosmetically reproduce the original part, CNC is going to be a lot more practical for a small run like that. I imagine you will probably want to work with two...
Is the car still there???
-Mark
Do you have an upright/regular seat mounted in there? I am surprised that would fit!
-Mark
Sorry, that's what I meant. An FM Dwarf, I get the Dwarf and Legends confused some times.
-Mark
If I wanted a fun, fast at autocross, cool, and cheap car and was not overly considered about classing - I'd strongly think about a Legends car. They make great noises, with proper slicks are pretty...
You might consider checking Woodward to see if they have an option - they make an "Ultra Light Manual Rack" which I think is common in FSAE applications and might also make sense for your car. If...
The vacuum powered blipper actually moves a pushrod which then pushes on the throttle mechanically. I suspect it'd be legal.

A robust and simple option is to add a 1/8 NPT into your existing brake lines (I used the spot where my rear hardline split into two softlines to the rear calipers on my old car) using a Tee like...
P1 allows DSR aero and then some.

Or ditch the beacon and buy a GPS system from Dave and Ellen at Veracity :)

Sound is not a good indicator of when to shift on such a high revving motor - try to train yourself to use the shift lights.

My understanding is that the latest generation of motors produce more power than the 08's did when modified/built. However, there is a lot less left on the table for aftermarket improvement. If you...
I don't think you are interpreting that correctly. That is the data that is required for SCCA to consider adding a formula to FX, not data required for existing cars which are already classified in...
I have a sports racer but the concept is the same - I basically am comfortable putting them anywhere where the floor has a bolt to the frame as I know that spot has strong core material there rather...
At least in my budget - for "low stands" - a single 4x4 cedar fence post cut down to 2x 30" wide makes for a sturdy base at almost no cost at all. I pretty much just use these when I leave the car...
Just as a data point - many of the front running motorcycle-powered P2 sports racers are going through an engine update from the "standard" 2007-2008 GSXR1000 to the newest 2016+. I have spoken with...
The Pirellis are great. On the other hand, I have been downsized from the role of "Maniac Co-Driver" so...
-Mark
I can appreciate your point Jim, but pretty much autocross is the only place where the R25B is used now since the road racing guys are on the spec radial, and everything overseas is treaded. There...
Just an aside, and sorry to Tom if this is cluttering his thread, but if I were an active CM competitor and owned a FF, I'd be thinking long and hard about petitioning the SCCA to allow some...
Sorry my friend, Phil and I are in "Pirelli Land" now - no Avons on our cars. We run Pirellis for autocross/hillclimb and in my case Hankooks for time attack and other open track events.
-Mark
We order tires out of the UK regularly - overseas shipping is no big deal and really doesn't require any extra effort. If you're after the arms, just order them, nothing to worry about!
