Robispec TIME ATTACK Build
 

GAME ON
Robispec TIME ATTACK Build
For those who don't know who or what Robispec is, we are a chassis shop that takes pride in making cars handle better than stock, have consistant handling charactristics, and allow the cars driver to have more feedback before things get outta control.

For this build we will be using these criteria.







Does the modification/deletion make our FRS:

1. Safer @ the track
2. Faster @the track
3. More Reliable @ the track
4. Lighter everywhere (not always the same as #2)

What will have very little to no influence for this build.

Does the modification/deletion make our FRS:

1. Keep the WARRANTY? (if you want one KEEP YOUR CAR STOCK)
2. Quieter (intake brakes exhaust come to mind)
3. JDM cool
4. Looks over function (We like looks but like going faster more)
5. Easier to Daily drive
6. More comfortable to daily drive
7. Sexier to pick up girls with

So with that short intro let the BUILD BEGIN.

First order of business will to be getting the handling sorted out

This is what we have done so far.

Lowered the car 3" ( and Center of gravity 3" too) with a combination of tire size and custom suspension components that yield stock camber gain curves,lowered Center of gravity, corrected roll center, bump steer,anti dive, wider front track width, and stock travel on the suspension (though we do change the compression vs droop limits). See cliff notes above.

I was able to take the car to the local dealer and get side by side shots.

SO here are some NEW picts and info on our SUPER HEAVY DUTY COOLING UPGRADE READY TO SHIP TODAY

At Robispec we are fans of extra credit work and so we went to an "overkill cooling solution" stock radiator is 15mm core we replace this with 2 22mm tube core add a liquid to liquid oil cooler in the "cold side tank" and have less than 2.5 feet of total lines to complete the whole "kit".
The best thing about this is that you dont need to thermostaticly control the oil temp (a big potential problem with the Air to liquid cooler solutions) as the water thermostat does this for you and actually heats the oil faster during warm up then stabilizes it to run about 20-30 degrees hotter than the water temp. this is better in many ways than the current kits on the market.
1. lighter overall
2. short hose runs,minimal resistance to flow = no extra strain on the stock oil pump
3. "fixes" the Water cooling issues sure to develop with the stock radiator.
4. Uses existing cooling airflow and leaves fender locations for brake ducting
5. Uses all factory connections/hoses fits with bumper beam and all plastic parts
6. Works with VORTECH and almost all aftermarket intakes and the Stock air box (PM for fitment details)

here are the cores for comparison. BIG PROBLEM and no oil cooler included with the car either.
Even the A/C condensed is thicker than the Stock radiator!(3/4" vs 5/8 ")

Enugh action??

Looks fast (as opposed to great :thumbsup:).

Have you taped over just the blanked out portion of the grill in front of the radiator, or extended down to reduce air flow slightly? That red tape looks to go down a long way.

Also, any before and after fluting under bonnet temps?


Subscribed

How did you get those vents in the bonnet? It looks a little neater than what could be obtained just using tin snips.

moves alot more air so I block off 3/4 of the grill both for wind resistance and front downforce
http://i240.photobucket.com/albums/f...ps5a118c95.jpg

just for you!

http://i240.photobucket.com/albums/f...ps694732df.jpg

it is a die that stamps them out one at a time major PITA
I have a guy close that does these for the rock crawer Jeeps so I hit him up!

Yep, I thought as much. I'm really interested in the pressure and temp differential as I'm also looking at some venting.

Whoever did yours has done a really neat job.

Looks good...

I heard you guys deleted both front and rear bumper beams and was wondering if any bracing was used in their place or not.

Also, do you happen to know the weight of those stock bumper beams?

Looking forward to your radiator/oil cooler group buy...

Thanks!

Makes me want to get one of these cars even more now. Nice work! Can't wait to see what else you do with it.

Lovin' the radiator/oil cooler setup!

Nice are you going to be selling the front and rear brake setup?

Sub'd for the radiator setup alone....

i think you guys need to get a protector plate for that rear diff, holy smokes is it low to the ground.

Got to Ride in this with robi . Awesome work car is amazing on the track and robi is probably border line crazy behind the wheel on track. After a track run with him it's truley a testament to our cars and his great design and suspension work , I highly recommend robi ;)

No bracing needed (you need to PROVE to me a bolted on brace is needed before I give back any of my hard won weight reductions!!!)both end beams held on with 4-6 6mm bolts these just hang them in place lol cant add any meaningful torsional strength. I mean we had a viper with a 10 point engine cage 6 on the firewall with 5/8ths bolts holding it to the fire wall and it STILL MOVED on a 7 post rig! we had to make interferance cones and press the hat on to the cone with the bolt before we lost the flex!
think I have them somewhere and can weigh them
Robi

agreed already have drag marks! but the iron case has a thikend area designed to take the hit while protecting the aluminum rear cover..But we ARE testing their design criteria!

RObi

Nicely done! Always lots of respect for robispec!

- Andrew

Glad to see you here and doing things for the BRZ!

In for vids of corkscrew at laguna seca.

Love your work Robispec and thank you for the fantastic late night alignment! I could really feel the front end bite on the corners and the car was nowhere near as loose as I was expecting. Overall, it was very planted and handled Laguna very well. I ran a 1:58 in an otherwise bone stock car. I'm looking forward to bringing my car back to you for more suspension and chassis goodies.

Anyone looking for an alignment in the Socal area should defintely take your car to Robispec. The man knows his stuff and his car is beast in the corners (my neck was working hard to keep my head on straight during the ride along with him at Streets of Willow lol).

-Mike

In for videos.

In for lap times on Willow & Buttonwillow.

In for more on the cooling setup.

In for more on the suspension bits.

Love how @robispec never holds back. :)

Getting a go pro...vids soon!

:burnrubber:

I met Robert Fuller a few times. Good guy. Fast guy. Saw him on 2 wheels in an EVO at Summit Point back in 2007 ! Fearless.

Another time we ate some burgers at In and Out half way between LA and Long Beach ! Good times.

He can build a car and drive it fast.

Hope all is well my friend! Good build. Car is WACKED !

MORE to come!

I notice that you're a second quicker around BRP on the NT-01s. Useful to know. Someone in another thread wasn't convinced.

Oh, and nice times. So close to 2:00 on the stock motor! :)

Off topic but...

I met Robert Fuller here in Dubai. He was famous on EvoM amd I had an Evo so it was like having Elvis in town for me. Guy was totally unassuming though - Santa Claus loke figure in a beat up T shirt and super greasy fingernails among a whole bunch of local racer folks in their very spotless fancy team-branded outfits. Robi might or might not have shaved or slept in days but that man was wrenching on cars non stop like a machine. He just came in for a few days but made some fancy race cars (and a few street cars) much faster. Some upsets in the local championship ensued later on and nobody knew why. I LoL'd.

Before he disappeared back to the states I managed to corner him in a pit garage for literally a couple of minutes between his wrenchings on the customer cars to ask him some probing Evo related questions even though I was just some Joe Schmoe and keeping in mind that I had no clue when the poor guy might have slept or eaten. He doesn't remember me but he shaved a good second a lap for me so I remember him, ha!

Class guy. Down to earth. Real deal. Etc. :)

RS3 is a pretty damn good street tire. :thumbsup:

Tire sizes? I'm mostly curious about the RS3 vs NT01 at BRP13CW.
