Robispec Mod Class Time Attack evo9 build
A couple questions on the build/NASA rules:
1. What is the "Mod" class that you are talking about? There is TTU/S/R and then the TTA thru H classes. I assume this will be in TTS b/c of the weight reduction work and motor build?
2. Re: the question re: Lexan - it is allowed everywhere except driver and passenger doors, in all NASA classes (incl TTA-H). Anyone know why they require glass (seemingly more dangerous than lexan) in the most dangerous area (near the drivers)...and then require you to drive w/the windows down??
3. I can't find the fuel cell reference in the rules, but from what I remember they are allowed as long as they are mounted within 10" of the stock tank (though I may be mixing rules w/diff organizations).

NASA is a different group with different rules.

My bust.....Sorry misread...
SECTION 5 – MODIFIED CLASS
The Modified Class allows a greater level of modification while still maintaining the brand and model recognition of a particular vehicle.

5-1.3 Transmission components may be upgraded with OEM or aftermarket parts.
5-1.4 Sequentially shifted transmissions are not permitted. Original equipment “SMG” style transmissions are permitted only in the vehicle original equipped with “SMG” style transmissions.
5-1.5 Final drive and differential type is unrestricted.
5-1.6 Engine performance upgrades and engine swaps are unrestricted. The rules in Section 2-3 apply concerning type of engine and number of engines.

5-1.8 Relocation of the engine and or transmission is not permitted.
5-1.9 If an engine and or transmission swap is performed the new engine and or transmission must be installed as close as is possible to the OEM engine and transmission location.

5-2.4 The following body components may be replaced with lightweight alternate components: roofs, trunk/deck lids, hatches, doors, hoods, front fenders, bumper covers, rocker panels. Rules 2-6.10 and 2-6.11 will be strictly enforced.
5-2.5 Rear aftermarket over fenders and fender flares may be installed. Rear OE fenders may only be modified to allow tire clearance. Vehicles with bolt on fenders or quarter panels may replace the entire fender or quarter panel with alternate parts.
5-3 Aerodynamics
5-3.1 Aerodynamic aids are unrestricted excepting rule 2-2.2 which still applies.
5-3.2 Only one wing is permitted.
5-3.3 Active aero is permitted.
5-3.4 Full under tray/ flat bottom is permitted.
5-4 Frame and Chassis

Attachment of camber and or castor adjusting devices is unrestricted. The OEM shock towers must be intact and the shock mount must pass through the original hole in the towers. The tower may be modified to install shock mounts, reinforcement or spacers but the OEM structure must remain in place.
5-4.2 Suspension pick up points may be moved a maximum of 1”.
5-4.3 Modifications to the frame and chassis to allow for proper suspension travel are permitted but are restricted to those modifications necessary to accomplish the above.
5-4.4 100% of the factory “floor pan – floor board” must remain in place as OEM. This applies to the “floor pan – floor board” from the front firewall to the rearward edge of the trunk compartment. The only exception is to allow for the installation of an approved fuel cell.

5-5.5 All interior components behind the driver seat may be removed. Headliner and carpet may be removed.
5-5.6 Rear doors may be “gutted” so long as the driver is positioned fully forward of the rear doors.

5-6.7 Active suspension is not permitted. Active suspension is defined as having automatic adjustment of ride height or shock strut damping characteristics. Vehicles with OEM semi active or active suspension are permitted to use the OEM system in an unmodified form.
5-6.8 Driver adjustment of the suspension other than the sway bars is not permitted while on the racing surface.
5-7 Roll Cage
5-7.1 A six point roll cage with side impact protection is highly recommended.
5-7.2 Rules in Section 2-6 will be strictly enforced.
5-7.3 The roll cage may penetrate the firewall. The firewall must be sealed.
5-8 Safety
5-8.1 If the vehicle is equipped with a six point roll cage with side impact protection the driver must use the following safety gear.
A. Fire suit with a minimum rating of SFI 3.2A/1
B. Gloves with a minimum rating of SFI 3.3/1
C. Shoes/boots with a minimum rating of SFI 3.3A/5
D. Head and neck restraint system or device with SFI 38.1 certification. Hans brand device with FIA 8858-2002 is acceptable in lieu of SFI 38.1. Older Hans devices must be updated to “post type” anchors.
5-8.2 Onboard fire suppression system is highly recommended and may be installed in place of a fire extinguisher.
5-9 Tires
5-9.1 All vehicles are required to use DOT approved treaded tires with UTQG tread wear rating of 50 and above. Section 2-5 applies.
5-9.2 Tire warmers are not permitted.
5-10 Miscellaneous
5-10.1 Air jacks are not permitted.
5-10.2 If front door glass is installed both front windows must be in the fully down position while on the racing surface.

I think we'll be sticking to the west coast events. Here are some pictures from yesterday:
we had the valve cover powdercoated orange:

Here's the back of the car. you can see that it's pretty wide and has sticky tires:

JRZs, a big swaybar, and spherical bearings in all the suspension links:

It and our Z were both at streets of willow today:

I was not at the track, though, because I had something else to work on:

If you don't mind giving out a ballpark figure - how much did the white/orange car cost to build (not including the engine)? The fancy parts/main mods on there are the Brembos, the JRZs, the spherical bearings and the rear composite doors?
Another question - do you guys run mostly stock ride heights? Seems like there would be an issue with rubbing the front unibody if you went much lower.

i have nothing but praise to say about robispec and road race engineering. we were out at the track today with this badboy and this car was so easy to drive but yet so capable. my skill level is no where close to the capabilities of this car, maybe if i am lucky i am at about 50% of this car. but nothing time can't fix.
i took alot of pics of the car today to make my own post, to give credit to robispec and road race, but it's going to have to be a different day because i am way to beat.
to answer the question about cost, i don't know if i could just set a simple cost on all this. its been a process.
