Building a SSCA T3 Car
I just purchased a 2010 SS with out engine and transmission from an auction and looking to build it into an SCCA race car out of it. This class is very specific on what you are allowed to use for suspension.
In T3 trim this car will have to run the LTT / LFX V6. I figure this is a good place to start since I'm on a budget and can always move up to T2 by replacing the V6 with a V8 and changing the rear gear. Here are the allowed changes: 800lb max spring F&R. SS front fascia, spoiler allowed. 1LE-SS Track Pack permitted part #23123398 . Tower Brace 22756880, red. TPR rear upper shock mount #22122, Pfadt lower control arm reinforcement # 1410135, Dry Sump kit # 009-92200, Brake Kit SS (p/n 23120542) For 2011 cars adaptor kit p/n(23484878). My question to you guys / gals are what spring rates y'all think I should run. This will be a racecar only and street ability is not needed. I will be running all of the options listed above available for the 2010. Last edited by Natebrod; 08-17-2016 at 12:08 AM. |

On spring rates...first question is what dampers can you run? Are you ONLY limited to the 1LE kit? Second is what mounting geometry changes can you make? I.E. can you do camber/caster modifications such as plates or are you bound to the factory adjustments? Good luck!

All the wiring that I need will be from the engine harness to the engine CPU. The only other functions I'll need will be brake lights / head lights.
Modifications to the suspension are pretty limited. From the Rule book: "A maximum of 3.0 degrees of negative chamber is allowed on front and rear suspensions. Strut suspensions may de-camber wheels by the use of eccentric bushings, eccentric bolts (crash bolts) at the strut-to-spindle, and/or by use of slotted adjusters at the top of the strut mounting plate. If upper strut slotted plates are used, they shall belocated on existing chassis structure, utilizing the manu- facturer’s original bolt holes and may not serve as rein- forcement for that structure. On other forms of suspen- sion, camber adjustment may be achieved by the use of shims and/or eccentric bushings. Slotted ball joints on A-arms on double wishbone cars may be used for camber adjustment only. b. Springs, Anti-Roll bar(s), and Shock Absorbers 1. Springs and anti-roll bar(s), shall remain as manufactured unless an alternate is listed on the vehicle specification line. Cars where air conditioning units have been removed shall refer additionally to Section D.3.b.1., above, for additional spring requirements. If alternate sway bar(s) are listed on the specification line, adjustable end links are allowed. The length of the link must be within 1” +/- length of stock. No modifications are allowed to the mounting point(s) other than to accomplish attachment of link. There may only be (1) rated spring per suspension corner. In addition to the main rated spring, there may be a “helper” spring on cars allowed a maximum spring rate on their spec line. Helper springs keep the main spring snug and feature a very soft rate, on the order of 10 lbs./in. 2. The make of shock absorber may be changed. Their number, perch location(s), system of attachment, and attachment points shall not be altered. Their type (tube vs. lever, etc.) shall not be altered. The interchange of gas and hydraulic shock absorbers is permitted. T4 only: (unless specified on spec line) Any non-adjustable shock absorber is allowed. The shock must be installed in the original mounting locations. Remote shocks are not permitted. Threaded shock bodies or adjusters may be used. a. The mounting hardware utilized shall be of the original type. b. The use of any shock absorber bushing material is permitted. Note: the bushing attaching the end of the strut to the body or frame on a strut-type suspen- sion system is considered a suspension bushing, not a shock absorber bushing. c. T2 only: minimum ride height is 3.75” inches. T3 and T4 only: minimum ride height is 4.5” inches. Ride height to be measured without driver at the lowest point of the rocker panel, but not to include welded seams or fasteners. d. T2-T4 only: Cars with alternate spring allowance in spec line, may use adaptors, and threaded perches to allow fitment of springs." As for just building a T2 with a V8 instead of the T3 V6 car it just comes down to money really, I figure the T2 car will cost roughly $12k more than the T2. They allow more modifications like ZL1 brakes, Z/28 aero, and Z/28 suspension. Not to mention the cost of the V8 being 5k more. I want to really work on driving skill right now. Plus go out and dice it up with V8 mustangs and porche boxters! |

I would tell you to talk with Justice Pete. He has helped me the most compared to any other vendor around. You tell him your goals and he helps you achieve them. He is very knowledgeable to the point that the GM engineers used his offsets and other stuff when they created the z/28 5th gen. I trust everything he says.

And if they're not going to let you change the strut mounting style but let you change the springs, the only solution I can come up with other than custom springs is to run Z/28 springs, which are about 300 lb/in front and 450 lb/in rear, and call Pete to figure out how to mount them. I'm running 450 lb/in front and 600 lb/in rear on my daily driver, but I don't know how you could even get close to that with a stock style spring.

The car is enroute from Texas, I'm in California. I'll be gutting it as soon as it gets here. I'm thinking next week sometime. I hadn't really thought of abs because the other classes I have run didn't allow it. It looks like abs and traction control are both legal in this class. I'll have to do a bit of research to see what I can do about keeping them intact. The spring rates can be changed up to 800lbs front and rear. The spring has to be stock style but can be a different rate. |

Nice.
So, I think I'm a little confused by the ruleset bits. But nevertheless here's my .02. If you are limited to the 1LE dampers, the safest w.r.t. rules and thus far most effective solution is the aforementioned Z28 lite setup (1LE damper, Z28 spring [RE:JPSS]). Else, the rules might allow a creative solution. Again, pulling from my fbody days. We used to use weight jackers with springs meant for a roundy round car (grassroots oval stockcar). It would not be hard to source a spring the right diameter, height, and rate for next to nothing that would "work" with the stock perches. The springs we used were like 50-60 a piece and the weight jacker was about the same a corner and allowed us to corner balance. You might explore that option. This being said if you don't upgrade to a Koni yellow the Z28 spring will likely be about the top end for what a 1LE damper can handle anyways...might be a moot point lol
