I just sold my 77 buick and I'm getting ready to build a 77 malibu. The springs I ran on my buick where all racing springs the lf 1000 rf 1200 lr 250 and rr 200 I also used pro shocks. I ran the car on a half mile for the 2nd half of the season while I had the car and the car ran great didnt bounce or anything. Should I use the same set up? Cause I was thinkin about running lf 1200 rf 1400 lr 250 and rr 200 and run afco shocks. The car needs alil roll going into the corners but personally I think the springs are gonna be to heavy. what do you think? I'm just tryin to get a few opinions just to see what everyone thinks. Thanks Joe

Well I run 255/70/15 all the way around the track no stagger. Hardly anyone uses stagger at my track. I run a 2" offset on the left rear and the rest are 3".........

If you want a little more roll, you might try a 175 on the right rear.

Well I'd try that but the rules state only 255/70/15 255/60/15 or 235/75/15. Been thinkin about running the 60's cause there wider than the 70's.. I really apperciate everyones ideas and opinions please keep them coming.........

I recently purchased a set of scales and took all kinds of info down for research. I run this in a 79 Monte
LF: 1000 lb spring, stock shock, 956 lbs on scale
RF: 1100 lb spg, pro shock, 715 lbs on scale
RR: 200 lb, stock shock, 669 on scale
LR: 250 lb, pro shock, 735 scale
Total 3076 with me,
I run weather masters and eagles with offsets on the rims of LF: 2 in, RF: 2 in, RR: 1 in, LR: 4 in.
the percentages:
Left- 55%
Right- 45%
Rear- 45.7%
Cross- 47.2%
This worked really well for a tacky on bottom and top and dry slick in middle. I am working on the heavy track setup. I have some time on the tracks but didn't have the scales when I needed them.
Are the wheelbases the same for these cars the same? I believe mine to be 108 in

my 77 buick was 112" the 79 monte carlo is 112" or maybe a lil bigger. I apperciate everyone that has replied. I just got me a car with a cage,seat, gauges, and a good body for $40.00... Guess it helps when you know someone that has 4 race cars and they are needin to get rid of 1 bad.

OH Yes,
that is one of the big cars, Well, if you can get some set up sheets from someone running one of these, you should be in good shape, I loved the 76 Monte I ran, I think the bigger cars are easier to set up. At the same time thou, the metrics around here are doing all right, it just takes a little more work to get them set up.

Yeah I miss the 77 monte carlo I totaled last yr but came back 2 weeks later with the 77 buick. Yeah it seems like everyone is going to the 80 model sytle cars so I had a good friend of mine sell me his 81 cutlass that needs to be set up. but it has the cage and the seat and everything else just need to set it up. so if you all have anymore opinions on the malibu keep sending them cause I'm gonna build the malibu too...

I wouldn't try the 60 series tires. There not really wider the first number is the width 255 the second number is the series or percentage 70 means the sidewall height is 70 percent of the width of the tire. So the 60's just have a lower profile and they wont flex as much. It would probly ruin your set up.

if i where you and my old car worked i'd stick with what i knew worked i've seen guys that change everything under the sun for the next year and by mid season they still don't have anything figured out and go back to what they know works and do alot better. i think it's kinda funny how guys think they need to update there chassis every year when we haven't changed a thing in our design in 5 years other than the fact that we can use smaller tubing in the front and rear bars now but we still put them in the same places

I see alot of people changing setups alot around here and they seem so lost. I was just trying to get some opinions on what I should use or try. But I just traded a tci transmission for another car and it's a 81 or 82 cutlass all I gotta do is put a new hood and rear bumper on it and paint it and Im race ready oh yeah and rear springs. But I'm stil gonna build the Malibu just when I find time. I've ran the same set up for 2 yrs and it worked really great on tacky or dry slick just I couldnt run the bottom it would also push bout 18 laps in but I run the high line at Bardstown right next to the wall We call it the Kevin Wilson line..lol

Remember though, changing things around and trying different things is how we learn and become more knowledgable about racing. I have put a lot of time into learning as much as possible in the last 3 years while I have been in school, I now have a much better job than before and my knowledge of racing is much improved. I am looking forward to next year with the new modified.
