Title: Ladder bars Post by: Jyrki on September 02, 2009, 09:47:25 am I am in the process of getting my '65 street beetle back together after a break. During the break the car was converted to 32" Ladder bars + Strange coil-overs. To get the car rolling I put the ladder bars in the middle position (out of the 7 possible link holes) =>
- Instant Center (IC) is now 10.5" from ground. - With a 26" tire the axles are 13" from ground. - I have not measured the Center of Gravity (CG) of my car, so I cannot tell what the Percentage of Rise (PR) is. CG should be close to any lowered street beetle (transmission is raised 2½", front is lowered 4", weight distribution front vs. rear is close to any standard beetle). - Springs are 800lbs - please note that the rear is narrowed pretty much and therefore the coil-overs are leveraged. I also have an option to replace the springs with 750 or 850lbs if needed. - Anything else I should mention? Car weights a bit over 2000lbs, ran 9.80/140mph with torsion bars (poor 1.5sec 60 ft)... What I am looking for is baseline for IC to get started. THANKS, Jyrki Title: Re: Ladder bars Post by: PPRMicke on September 03, 2009, 14:00:51 pm I am in the process of getting my '65 street beetle back together after a break.

THANKS, Jyrki I think 800lbs (362.8kg) is too hard on the car weighs 2000lbs (907kg) I am living in prostock / promod racing think you can use much softer rear springs (a prostock us about 150kg springs back as the starting setupp car's weight is 1066kg weight distribution is 50/50) How much considering the car's rear wheels pc //// PPR Micke Title: Re: Ladder bars Post by: Josef on September 17, 2009, 20:12:50 pm Hi Jyrki
Do you have any pics of the ladder bar/coil over mounting? /Josef |
