Robispec's Ride Black FRS Time Attack Mule
 
OUR DETAILED BUILD THREAD IS RIGHT HERE

http://www.ft86club.com/forums/showthread.php?t=28180

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.

This is what we have done so far.

Lowered the car 3" 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 and stock travel on the suspension (though we do change the compression vs droop limits).

I was able to take the car to the local dealer and get side by side shots. We also had it out to the Redline time attack but showed up late and ran in the rain shower session...I did have a member here drive the car and get his impressions He can chime in if he wants to.

Looks a great, but a little too low for me. It also appears that it will fail to traverse any speed bumps!

been waiting for this post ever since I heard rumblings of you guys getting a car. Verrrrrry excited~

Thanks we also have a HUGE radiator in the stock location with a included oil cooler..and still have the AC condensor working (we live in the desert too). stock radiator is 5/8" core (yes you read that right)..the new one is 2.5" Nascar core...car weights now 2525. looks stock inside and out..

Going for 2450 with the next round of modifications.

Any info on the exhaust? Looks interesting

Robispec!!!

I met you here here while you were here in Dubai a few years back working on the Touring cars & stuff...one word...awesome!

Curious to know what bits you stuck on the car to oreserve the geometry at that height, which dampers you're running (assuming Robispec KW V3s), what you're doing for aligment....in short...everything you care to share!

Glad to see you on here & will be watching your development work. :)

we made a 3.1 KG aluminum cat back for our race car and it survived 30 minute sessions quite well... 70 degree farenheit ambiant temps.
Engine out, custom SS header,"V"banded to a transision pipe for NA or SC applications. (the header can be used for NA SC or Turbo apps) over pipe and catted section weighed in (with the alu rear) at 9.1 KG complete. engine back.. time will tell on the durability. We are a chassis shop so we made the lightest part possible. you can just see the 2.5" aluminum muffler and tailpipe just peeking out.

If we get enough interest the header and transision part are possible
We got 25 whp with this an Intake and ecutec tune NO CEL's

Glad you remembered me!
Front end uses
  • Robispec modified Ground control topmounts (gets us to 2" higher upper strut mounting points).
  • Robispec custom lower control arms with track, camber, castor, and roll center adjustment/correction (all on spherical bearings).
  • bumpsteerable outer tierod ends.
Rear end uses
  • Custom Robispec upper damper mounts adds 2" travel to the rear suspension.
KWs with inhancements ;-)

Basic "fast/safe" RWD alignment..straight where you can get away with it, toe in for stability if needed.

I'd say that's probably w/ an empty tank as well? That's an awful lot of weight for the mods listed.


Also, the mods you still have planned will be fairly significant (my LithiumPros batt alone will save ~25lbs).



Getting my car prepped for Nat level SCCA Solo work.


Thanks for the reply!
