I dispise hood pins. That is one of the main reasons I haven't changed hoods yet.
But I will say, those suck less than others.
I'm not a big fan either since for the last 15 years I've had Dzus fasteners holding my cars together(they weren't long enough to use on this hood). I had to use soemthing to stop the hood from lifting at speeds above 70mph. the ram air puts a ton of pressure under the hood making it very unstable above 70mph...and down right scary above 100mph!!
Old school pins don't do it for me. I like that these are composite/aluminum=no rust and there's no pins to loose or lanyards to scratch paint.
I'll find a pic with my hood shut and post it later.
the traction bars just need some additional testing to back up my initial results but they definitely work.
the bars are like an old school traction bar with the benefit of having the ability to adjust preload.
In a nut shell what they do is shorten the instant center(IC) to the front LCA bolt. Normally these cars have an instant center located somehwere in the middle of the car and down low so it causes them to hit soft and squat during launch. Thats why we have the relocation brackets for the LCA's to shorten the IC.
I've been running these for over a year now and they definitely work. My 60' times are always in the mid-low1.70 range with a best of 1.69...thats an N/A auto with a TCI converter not even a manual trans car. when i removed them my 60' times immediately slowed into the low 1.80 range...replaced them and back in the 1.70's again.
Squat is non-existant in fact i now run my drag shocks set on full loose so it hits the tires even harder.
I still have to test them on a couple different combinations (and yes I already have tests set up guys) before I feel real comfortable about my results but I'm pretty sure that they will all respond in a positive way.
These aren't for everyone. If you have already spent the money and upgraded your entire suspension with race pieces(with rod ends) then I wouldn't recommend using these since you can just install the reloc. brackets and get decent results.
Now if you haven't done anything or just have LCA's and a stock or street type urethane upper then this will definitely help. It will eliminate the housing rotation seen with the stock UCA or big urethane bushings.
I actually unhooked my UCA completely while testing these last year and it worked exactly the same with no UCA at all!!!
Guys Please Do Not ever unhook the UCA like I did. I was trying to prove a point but would not dream of using them for that purpose alone. Leaving the stock UCA in place is more of a safety factor than anything else.
