  • Seen in Autosport

    I saw an advertisement in Autosport (Oct. 16 issue) from a company named Intercomp. The product they were showing was a scale system - total of 4 w/ electronic connection to a control module.

    Clearly this is a 'flat flooring' system as it's refered to over on blatchat. This got me to thinking....

    Have any of you guys out there flat-floored their cars? If so, where?

    My build should be done no later than the end of the year (I'm waiting on the loud part right now) and I'd like to start off w/ a dead level (weight distribution wise) car.

    Thanks!

    flat flooring, or setting corner weights ?

    10 years ago, I vintaged raced a Titan FF. The crowd I hung with then, mostly SCCA club ford & VARA vingtage ford guys, would use 4 digital bathroom scales, a balast equal to the driver weight, and a couple of us could do a car in a short evening in a home garage. Bathroom scales may not have the range for our cars. Also, this assumes adustable spring perch all around for easy preload adjustment. Ask the shop in your locale that services formula cars for leads. If your near San Diego, Bill Schlossnagel can probably do it, or Roland Johnson.
    I know their are shops in LA, the bay area, and likely Santa Barbara, and the bay area.

      That process is also referred to as "corner weighting". The San Diego Solo II guys have a set of scales and some do set up their cars for autocross utilizing this method. David L. prepares his 7 for autocross this way and it is the best handling, most neutral car I have ever driven :!: 8)

        Which is exactly (well, almost - I'm not sure if I'll be Autocrossing) why I'm looking to do this.

        Let's see, approximately 1100 lbs + ~200 for me + ~60 for fuel et. al. = 1360 lbs / 4 = 340 per corner roughly..... run into bathroom look at scale.... return... nope, our Kraut type won't quite make it. Rats.

        I'll do a web search and see what I find...

        Thanks!

          8 scales

          I have seen some older posts on Blatchat that people used 8 scales of the cheapo style (they said GBP 5 each) with 2 each per corner connected with a board and a roller on each scale. Otherwise the horizontal forces on a single scale can screw them up, anyway. Sounds a little cumbersome and I would not know where to find a scale here for 8 bucks.

            Moose etc.: David L. is usually very happy to share his extensive 7 knowledge with other 7 guys. If you would like to know more about set-up and corner weighting I can provide his phone #. He's a guy that is really dedicated to 7s :!: 8)

              I found a company in Torrance who's web site descibes that they will corner weight a car but I haven't called yet. Can't do anything until I have an engine and tranny anyway.

              Does David L. have a series 4 Lotus 7? I met a guy at a Rose Bowl Autocross several years ago who had one and as I remember our conversation he said he was from S.D. Anyway, if he wouldn't mind a call you can forward his number to [email protected].

              Oh, and I found some pics online (Google: enter 'corner weighting') of The Board n Bathroom (sounds like the name of a bogus pub doesn't it?) scale approach. Looked less than precise at first glance.

              Thanks!

                The guy in the series IV car was probably David's friend Red, who lives in Escondido. Another local gent, in fact a member of this club, also bought a nice series IV about a year back. David has a couple of Caterhams, one around 20 years old(for sale), and the other a "race" chassis about 5 years old. He has assembled and dis-assembled both cars many times and is a wealth of info on 7s and set-up. I'll contact you via the club messaging system with his #. Are you assembling a kit or re-building an existing car? 8)

                  It's a new kit, arrived in mid June. The car's a Superlight w/ all the carbon fiber bits etc. There's been some delays with the powerplant, which I expect to be ready to install fairly soon. Doesn't matter really anyway as the 500 licenses for the year are already gone, and have been for quite some time. So, lacking track opportunities between now, er, the end of next month (hopefully) and January I'm just sittin n' dreamin.

                  I'm really looking forward to that first drive.

                      My SLR has a zetec. If I were buying the car now it would definitely be set up for a Duratec! Lighter and oversquare :!: :idea: :arrow:
