68krolla Posted January 27, 2010 Report Posted January 27, 2010 My corolla is a primed shell at the moment which is the perfect time to mess around with the body. I'm wanting around about 300rwhp but a chassis stiff enough to support it so it wont twist or warp an launch! I have already started to seam weld and I'm going to make some strut tower braces and get sway bars! I think that it should be enough for what i want, and I'm trying to avoid using a roll cage because its overkill for my application and i want the car to be a cruiser not a drag car. Can i have some opinions about the seam welding, strut braces and sway bar, will they be enough do you think? or if there is any way of making the chassis stronger without a roll cage. Thanks boys!! ( sorry if there is previous thread about this, but i did a search and nothing) Quote
Nemesis Posted January 27, 2010 Report Posted January 27, 2010 I'm not familiar with the chassis on these cars, but perhappes welding in a pair of chassis connectors would help to stiffen things up a bit. Ive welded them into all manner of vehicles, really helps when the chassis is soft in these tin shoeboxes. these are along the lines of what I'm talking about. Quote
jason12 Posted January 27, 2010 Report Posted January 27, 2010 Even a 1/2 cage would help stiffen things up a bit and wouldnt be too intrusive Quote

Those chassis connectors i have heard of and they look about what i want. i just couldnt find any info! is there a reference page on the net or anything. I just need some sort of an idea to develop on myself! Oh btw how does this go against regulatios and all that bullsh*t! I don't really want a half cage because I'm sure that you have to register your car without rear seats! Quote

I don't really want a half cage because I'm sure that you have to register your car without rear seats! the ones pictured are mass produced for the new ford mustangs. in smaller old school cars (like my old gemini) the cars chassis usually consists of 2 halves, front and rear, and the floorpan acts as the joiner between the 2. I just take a few lengths of 75x40mm 2mm rhs and fabricated sections that are welded in literally joining the front and rear main chassis sections together. there really is no guide to it, every car is different.

So in the picture above is the left and the right side of the chassis connected or are they two separate pieces? and are they legal? Quote
Nemesis Posted January 27, 2010 Report Posted January 27, 2010 (edited) the left and right sides take care of themselves through the vehicles existing cross members. bolt in units should be perfectly legal as they don't really require any major modification (I recommend using crush tubes should you decide to bolt through chassis rails via existing holes), but weld in units definitely need engineer consultation and a certified welder to sign the job off once work is completed. here's an example of a serious job.

Yep making a bolt up frame is probably how i will do it then i can just take it off when i got to register it! As i said it will only be a cruiser but not to delicate at that. if i were going to 500rwhp then i would consider a roll and all but this should be sufficient. Thnaks for all the help Nemisis. you will find me experimenting on this after i have finished all the seam welding! Go to http://www.rollaclub.com/board/index.php?showtopic=35377 and you can head me in the right direction or what ever! Do you know of any sites that have any kit information!? Quote
