just to weight in , i built a 99 civic si , to replace the aging 92 prelude si.the civic looked appealing at 2360, far less than the prelude at 2715.after driving both i have to say the civic will not catch the fast rx7 or the e36.in four outings we were consistantly 2-3 seconds off the fast guys.with the prelude we were only 1-1.5 seconds off the same cars.so to add wieght to the del sol or civic is a death nail in ITS.two points to make,(1)the formula for determining roll bar tubing goes out the window,since at 2360 the tubing size is 1.5x.095.when you add 220 lbs. the roll bar size goes to 1.75x.095 or1.75x.120.so is the cage that i had built leaga ?(point 2) our car will need at least 160lbs. of ballast, where does all that weight go.are these points factored into the formula for determining weights in IT. J ust my thoughts on the subject .timmy chapman

I do believe we've hit a bit of a sticky wicket with the roll bar thickness issue. As it is not clearly written, there is only a specification for where the weight is to be located, but I want to see how someone can safely mount 100 extra lbs. in the front floor board of a stamped steel uni-bodied car. What I hope not to see is something that causes that weight to come loose during competition. I'm sure that the formula for weight versus horsepower didn't include the change in roll cage construction.
