    In the December Fastrack:

    "The MAC is considering the possibility of allowing Legends cars (e.g. per www.600racing.com) to compete in class F Modified.

    Specifications of these cars are as follows:

    - Wheelbase: 73.00 in (1,854 mm)

    - Overall Width: 60.00 in (1,524 mm)

    - Overall Length: 10 ft 6 in (3,200 mm)

    - Height: 46 in (1,168 mm)

    - Engine: Yamaha 1250cc (sealed)

    - Horsepower: 122 hp (91 kW)

    - Weight: 1,300 lb (590 kg). with driver

    - Tires: 205/60R13 BF Goodrich Tires Comp TA HR4

    - Wheels: Width: 7” / Diameter: 13”

    - Suspension: Coil Over with Bilstein Shocks

    - Frame: Full Tubeframe with Integral Rollcage

    - Harness: FIA approved Five-Point

    Membership feedback is requested on this possibility, and on details of additional allowances which might be permitted for these

    cars. Such allowances might include tires, wheels, engine substitutions, limited-slip differentials, and/or suspension changes."

    It looks like a good match to me. I have some experience with Legends cars and they don't have independant suspension in the back like the V's or F440's but as long as they are allowed to change engines to something better than the 125 hp Yamaha FJ1200 engines that are in them, they may keep from being emnbarrased. Their suspension is Toyota derived and not very sophisticated but maybe with enough development, they would make a fun auto-x car. I would suggest that they be allowed to run alternate motocycle engines because the FJ1200 engines are becoming a little scarce and a good rebuild is expensive. Maybe allow any stock, production, naturally aspirated motorcycle engine with 2 valve limited to 1300cc, 4 valve limited to 1100cc. This would keep the Hayabusa motor out of the cars. I'd also let them run wider wheels and maybe change the rear brakes to disc. Of course doing any changes would mean the cars could no longer run in Legends racing, but no prepped Solo V can run in FV racing anymore, either.

    You didn't ask about the most important thing....tires. Would you still saddle them with the crap tires, or allow slicks? Would they tip over on slicks?

    Let's see.  They are narrower, have a shorter wheelbase and the same power to weight ratio as a solo vee.  And better front suspension.  A well designed solid axle rear suspension is better on smooth surfaces than the 1934 swing arms on a vee, too.  So yeah.  Let's give em more power and LSD.  

    No, they won't tip over on slicks.  Let them have slicks that fit on their existing wheels and see how things go for a couple of years.  Then make any need adjustments.

    BTW, our snowmobile powered competitors don't have independent rear suspension.  They are truly a solid axle, no differential.

    Yeh, let them use slicks. As for wheel size, aren't 7" wheels way narrower than what the V's and F440's use? I would think that at 1300lbs, they would need something a little wider. I didn't realize that the F440's had a solid axle, though.

    Agreed - allow them any tire and see what happens.

    I assume they can already change spring rates and shocks? If they can't under their rules, I'd allow that too so that they can tune for the slicks.

    It seems like it would be a nice addition to the class!

    Most Solo Vees use 20.0 x 7.5-13 tires on 8" wheels in front and 20.0 x 9.0-13 on 10" wheels in the rear.  Some of the F500 guys think we should try the  20.0 x 7.5-13 tires on the rear and 20.5 x 7.0-13 on 6" wheels in front to get higher tire temps.  I think most the the F500's are using 18.0 x 7.5-10 tires on 8" wheels front and rear.

    Tread widths:

    18.0 x 7.5-10   7.5"

    20.5 x 7.0-13  6.75"

    20.0 x 7.5-13  8.0"     Can be used by the Legends on their 7" wheels

    20.0 x 9.0-13  9.75

    Maybe let them use 10" wheels and the 20.0 x 9.0-13 tires.

    Legends shock rule:

    64. SHOCKS: All Legends Cars must use INEX (stamped with the INEX logo) Shocks as currently delivered by 600 Racing, Inc. Shock numbers must be made visible at the request of an INEX inspector. Changing or altering the fluid inside is illegal. Altering or tampering with the shocks, or competing with same, will result in a six (6) month suspension for both driver and owner. Shocks may be turned upside down and/or the upper part of the rear shock may be mounted on either side (inside or outside) of the frame. Shock bumpers are permitted (maximum 1/4” tall).

    Legends spring rule:

    66. SPRINGS:All Legends Cars must use 10” or 8”springs. Any spring weight combination and aftermarket springs of stock design are acceptable. Only one spring is permitted per shock. Spring rubbers are not permitted.

    I'd say let them use any shocks they choose.

    Legends must use a locked differential.  So, it is a true solid axle like the 500's.

    Sounds like an interesting proposal to me. At minimum, a few Legends cars would up the "cool car" quotient at events. ;)

    I can't see allowing different engines or other significant drivetrain/suspension changes. However, you just about have to allow slicks for them to be remotely competitive.

    I agree, Legends cars look cool and you can buy a brand new, ready to race car for $14,000. After thinking about this some more, I take back what I suggested about changing engines. I would hate for a bunch of Legends guys to enter a competition with their INEX legal engine, just to be smoked by some guy who went through all the trouble and expense of putting a liquid cooled R1 engine in. I still think that they should be allowed to run wider wheels, adjustable shocks and slicks because those are all easy bolt ons and only make sense in a Mod class. There's enthusiasm over on the Legends forums about this, too. Maybe we'll see more people racing in Mod class in the future?<!-- / message -->

    Agreed on several points. I would allow it run different wheels and slicks, and maybe open shocks/springs.

    You could realistically have a fun little car that could run track days, circle track, solo, and hillclimbs. Couple different sets of wheels and tires for specific venues.

    Don't forget bracket racing and ice racing for those of us up north :)

    Got to drive a legends car this weekend on our test and tune course. Man that thing is nuts. Started out with the Oval guys were making laps on the ajoining 1/4 mile oval. we were making runs on the parking lot in our cars.

    as true gear heads will do pretty soon the oval guys were watching and commenting on "that looks cool". Anyway one thing led to another and it turned into a king of the hill in our kids FJ Kart then the CSP Miata and BS Boxster S. After the driving lesson was handed to the oval guys they offered up the Legends car for a couple runs in the cones. They went 1st and then with some arm twisting I jumped in.

    Dang good power and despite the car stuborn will to trun left by it's self I had a blast. Just thinking man this is almost as fast as my XP 914. and probably would be lots faster on slicks and a squared up suspension.

    we are probably going to host these cars at our local events Maybe I can work out a co-drive [:D]

    I'm not so sure FM is the right class for them though.

    They are considering Legends for FM or DM but I thought motorcycle engines weren't allowed in DM? Where do you think they belong and why? Here is what it says in Fastrack "

    "The MAC is still seeking member comment on the possiblity of permitting Legends (and perhaps Dwarf) cars to compete in

    F Modified, or possibly in D Modified. See the December 2009 Fastrack, page 60, for details."

    FM seems like the better fit.

    In DM they'd be thrown in with cars having twice the horsepower or more.

    In FM you can play with the minimum weight to reach some sort of parity with the Vees and F500s.

    In 2002 I ran my Legend car in DM at several midwestern solo events (Tour and Pro). I sat it up to run my DM 10x13 wheels and Hoosier 20x9 slicks. It was a LOT of fun, but not overly competitive.

    IMO: the only way they should be allowed to run is with very limited modifications from standard INEX rules, such as slicks on the standard wheels.

    Second opinion: They won't be Nationally competitive in any Mod class.

    Aren't the Inex legal wheels pretty narrow? Would a Legends be competitive in FM with wide slicks on wider wheels?
