muvro Newcomer Location: Sydney Registered: August 2005	Re: Roll Cage Designs - AE86 / KE70 Specs Sun, 28 August 2005 13:29 Thanks for the congrats HotGemini, Yeah I don't disagree that a comprehensive cage gives the vehical better dynamics, both through handling and drivability. The point I was making was that the difference between a cage with selective design compared to extreme design is minimal. You compare a bolted in alloy cage versus a welded in steel cage. Two very different setups. Any bolted in setup won't do alot for you in terms of body stiffening. However there are other methodes of body stiffening that are extremely effective and don't add much weight. For instance stitch welding every seam in the car. Reinforcing suspect and known weak points, reinforcing suspension mounts. Most of these would only take a few welds to stiffen and not require extensive pipe work for much the same desired effect. 50kg is still 50kg. Also if the builder has little if no experience in cage building or vehical dynamics then the cage may not be built to take full advantage of it's place in the car. In no way am I disagreeing with you in the fact that a cage with X pipes is not more effective. But it doesn't seem that the car is being used professionally nor competitively just a car to have some real fun in. It definately has some mumbo! Being in a KE 70 (Why did I think sprinter...) for cams approval it's not to go into the boot and tie in the rear shock towers. One thing to remember is that without sufficient stiffening of the rear/front suspension having the center of the vehical extremely stiff without any flex can lead to major cracking of structual areas of the body. Namely rails and qtr panels. One thing to aid in stiffness is to tie the cage into teh body along the pillars. All three 'A','B' and 'C' pillars. TRhis will not only aid in stiffening of the body and for that matter the cage but will also help in keeping the cage rigid during a roll over situation. With regards to the hoops lower reinforcment, we always install a straight pipe from each side of the hoop. The diagonal meets at the cross bars attatchment point. Adding to the hoops strength. I have some pics of cages I have done if someone can host them. One in particular is a Group N car and with the installation of the cage from a bolt in to a full weld in the tranformation was totally amazing according to the owner. A well experienced driver. As said above not disagreeing with you at all but the sort of use this cage is going to see I think minimum is best. Use cost of piping and put it towards good tyres etc. In saying that don't skimp on it either. Pay great attention to reinforcing suspension components as HotGemini said the stiffer the car hte better the responsivness and improvment in handling dynamics. So long as the cars suspension is adaptable. tark [Report message to a moderator]
