Pathogen Posted October 21, 2003 Share Posted October 21, 2003 I am looking at putting about 300-350hp to the ground in my 240Z and am wondering how I can keep my chassis straight. I have a small paint crack above the 1/4 windows so I know something already needs to be done. Doors close reasonably good and so did the hood when it was on the car. I am going to do subframe connectors and strut tower braces. My question is will this be enough? I was considering putting in some sort of rollbar/cage that would give me some side impact protection as well connect to rear stut tower. This is going to be a street car and I dont want the cage to become a PITA to get in/out of car. Can I use 280Z doors which are alot stronger on my car instead of going with a cage? Or is a cage necessary? I would like to hear how much power others are putting down in their 240's and what chassis mods they have. I would rather do to much reinforcement then to little and then I have room for more power at a later date. Quote Link to comment Share on other sites More sharing options...
johnc Posted October 21, 2003 Share Posted October 21, 2003 279 hp to the rear wheels on my car and 275/45-16 Hoosier R3S03 track tires. It has the following: 1. Welded in 4 point roll bar. 2. Welded in rear strut tower brace. 3. Welded mounts and bolted in front braces that triangulate the front strut towers and the center of the firewall where the hood latch was. No rear c-pillar seam cracks, doors open and close fine, etc. after 11 years of racing. 3 years ago I did have to weld some stress cracks that appeared at the rear of the driveshaft tunnel.
