BLKOUT2: Rebirth. PRT 2011 track car build thread.

Did some more work today in preparation for the new camber adjustment system up front. I will be making adapters to mate S13 camber plates to the GC coilovers and then welding on new strut tower tops to match the S13 bolt pattern. First order of business was to knock out the factory mount cup. At one point I had intended to make my own camber kit but changed that up. I still had the top plates I had made for that so I threw them on just to visualize some things. I also did some mock up to start visualizing the new front end. Given the amount of access I'm granted without the core support I'm considering making the replacement pieces bolt-on to retain some of that. Additionally It could be designed as the fail point so should a collision occur the remainder of the chassis would be spared and I simply bolt on a new unit.

More reassembly of the front end components tonight and brainstorming the new setup. Overall the radiator is moving 1 1/2" forward in the car to provide better access as well as more clearance for the SC jack-shaft. I have the concept and design pretty well nailed down, now it's just a matter of getting materials on order. I may hold off for a while for the sake of getting some other projects underway, but at the same time I'm excited to get this project finished. Next up will likely be the new custom engine and trans mount designs.

Very cool!!!! Be careful not to add any weight. When we did my camber plates we also moved them back so we could dial in more caster. Just my 2 cents.

Thinking dzus fasteners like I did the rear corners. I like your latch, but I don't want to mess with the fender. Also gutting the rear bumper and making it QR too.
 
Any extra room you can gain to clear the vortech is very beneficial. I can tell you that installing a vortech with what's supplied with the kit was a pain. On a side note, I'm not sure the history or miles on your vortech but you may want to consider rebuilding the head unit and replacing the jackshaft bearings if you haven't already. Both of which are fairly easy and straightforward to do. If you have questions or want some rebuild links shoot me a pm. :)

I hear ya. I removed it all in car before I pulled the motor. My unit is brand new, only has 1000 miles on it.
 
Is this going to impact the weight distribution ? I had head the CSVT was a little nose heavy to begin with.

It will be lighter than stock. The majority of my weight reduction has been out back and the car is actually very balanced.
 
Stock weight distribution is 63/37, so yeah, very nose heavy. Although it's very easy to rapidly reduce weight in the front which you have done nicely.
 
Have you thought about making fender braces? they mount to the door hinge mounts and extend out into the inner fender, under the outer fender.

seems like something that would really stiffen up the front end quite a bit.

another thing you could look into is a bolt on X brace that goes between the subframe connectors.

just some things I've seen elsewhere that you might be able to design for the CDW cars. they'd also be marketable parts for people REALLY trying to get all the flex out of the chassis.

and last but not least, stitch welding the whole chassis, that would also stiffen her up quite a bit further, but not really be a marketable product.
