Well, due to the rain out last week, we had to do our preliminary setup at one of my least favorite tracks...Roebling Road. For many, this track is just plain uncomfortable and weird. It's basically several sweeping skid pad style turns linked to together by just one long back straight. It's a track that many, including myself, find very hard to get comfortable with. Attacking it is out of the question, as there are no firm easy apexes to spot, or visual clues. Oh, and just about every turn is off-camber...yeah!



Now lets talk about the good stuff. Roebling Road rewards patience, and smoothness. And if you can get a car to stick well at Roebling, it will be probably stick really well at just about any other track.



This was my first time using the Carbotech XP12 racing pads all around, and they performed perfectly. Terrific initial bite, and good release characteristics, and no fade. Of course, Roebling isn't a crazy braking track, but so far so good. The JRZ's felt very controlled with the 1000lb springs all around. We added 3 more clicks of high speed compression, and 2 more clicks of rebound, and the car seems to behave in a very predicatable manner for me. Absolutely laser precise turn in, ZERO understeer, and a very planted rear, that could still be rotating with a moderate to aggressive application of throttle. Trail braking and rotations towards the apex were also very easy to do. Pretty much the exact opposite of how the stock suspension felt.

And after a long day at the track, we headed over to Desposito's on the water, for some fresh crab, shrimp, and oysters. Here are the dead soldiers.



Let me know if you have any questions.

 

^ i see your shop has acquired a mobile dyno, very nice!








































































(for those that dont get it, he has an iphone.........oh yeah, it has an app for that)

 

what were top speeds on the straight? looked to be around 120 or so?

 

very nice sharif. took the viper out yesterday and of course i dont see any cars that would be willing to bite, and then today driving home from work i see the Forged GTR. i was angry

 

Always love track pics. Keep it up.

 

Mobile dyno....cute.

Speeds on the back straight were mid 150mph range. Vids never seem to capture the true speeds we are seeing.

Thanks Rick!

 

dupe

 

really. i didn't think there enough distance to hit 150...the GT-R must be faster than i thought...

sick vid, btw... makes me want one... or a REALLY fast EVO! *hint hint*

 

Yeah, it uses it mere 400-450whp very effectively, given it's lardy 4000lb mass it has to move around.

However, the shop/your Evo will walk it like I am driving in reverse. At least in a straight line..haha.

 

is this a follow up to another thread about the JRZ suspension? no clue on who they are.

 

Whoa...Jeremy, did you get a new toy?

BTW, nice vid and write up Sharif. Your making me more impatient about a GTR

 

that is...if you'll ever get it finished up for me...

we might have to make it handle better than the GT-R, too... not that i'd be able to steer it around the track properly...with me driving, it might as well be a lifted SUV...*haha*

 

not yet... waiting on the doctor of FI to bring the beast alive... it's possible that i may have an interim toy in the future, though... it's all up to Sharizzle...

 

I see. My buddy will be bringing his EVO down to the open house for a tuning session before hand.

 

Sorry, yes it was something I posted up on Nagtroc and the other GT-R forums. Basically, JRZ makes the coilovers that have won more Daytona podium finishes in GT that just about anyone in recent memory. It's the real deal motorsports damper company, similar to Moton, Penske, and others...only better, IMHO.

which model version of the JRZ are you testing? is it plated at all or one of their raw race models I see?

and very cool, they actually manufacture their own dampers. what about the springs? are you own your own supplying them?

 

Yes, each set is manufactured in their workshop in Holland...one at a time, and to order. We use Hypercoil springs, but there are other suitable brands as well. It's a standard spring, so it gives you different options on spring rates. Everything from a super soft 500lb, all the way up to 2000 lb springs.
I choose the 1000lb for my purposes.

Here are some pics from the installation.





Corner balancing before hitting the track:

You were the first to notice....LOL....I was waiting for someone to point that out. She's HUGE!
