  1. Hi guys, so my team just finished Sebring and we felt that the suspension needed a bit of work. We have a 1986 nissan 300zx, non-turbo. I'm trying to get some upgraded shocks for the car and ideally I would like for it to be within the 2X rule. I saw that according to the rules "The retail price of any NEW replacement wheel, brake caliper, brake rotor (1 or 2 piece), or shock absorber that you put on your ChampCar must be less than twice the cost of a stock replacement wheel, brake caliper, brake rotors, or shock absorber that is available on-line by a nationally recognized auto parts retail chain (i.e. - Napa, AutoZone, O’Reilly, Advanced, etc.)." My confusion here is that all of those retailers have wildly varying prices and I'm not sure which price to base the 2X rule from. Autozone alone has prices from $55 to $150 for a single strut. Additionally, what if the parts are not available from those retailers, such as for wheels, should the 2X rule price be based from the manufacturer website? Thanks!
  2. Seeing if there is wisdom out there that anyone cares to share. Tire temps (one sample - this was with our driver that is least hard on the tires which we think accounts for the huge middle to outer delta): Inner Middle Outer 164 157 143 <<<RF 161 156 134 <<<RR Tire wear (tread depth after two day race): 6mm inner, 7mm middle, 4mm outer <<<RF day2, was RR day1 These two indicators seem to be telling the opposite story about the setup... Temps say to reduce camber (to even out temps), Wear says to increase camber (to even out the wear). The car handles well, no complaints there. It also stops pretty well, but we suspect it would stop better with less static camber - still no complaints. Toe was 1/16"i n, we will likely go 1//16" out next race, don't know how that will impact wear on inside tire, but don't expect it to make a big difference. What would you do with pressure and camber?
  3. Hi guys, After Sebring, I did some comparisons between our corner speeds and some other cars, and we came up lacking. Even though we'd make up some speed on the straights, we were much slower is several corners. So, I went home and bought a ground control coilover kit for the Contour and took a grinder to the strut towers. We should end up with a heck of a lot more camber adjustment. My question is about suspension travel and such... How much is enough? The kit we bought has 600 lb/in springs in front that are six inches long. A recent test fit showed we were compressing them about 1.5 inches with just the weight of the car on it (which jives with out estimate of about 900 lbs per front corner and 500 per rear... Nose heavy pig). The springs are six inches. Coil bind is at 2.3 inches height. Load at coil bind is 1992 lbs ish. That gives us something like 1.8 inch of compression travel before the coil binds...is that enough? I'm thinking not since I would guess a hard weight transfer would throw around 5-600 lbs over, and it wouldn't take a very big impact to use the rest of that compression. On the other hand, would we regularly more than double the load on the front suspension? My gut says we need more play, but I was looking for some advice. Thoughts? Thanks in advance.
  4. Found a rear wheel bearing on its way out on the rear of my 240SX this weekend. It uses a bearing assembly with the flanges and bearings as a unit that bolts onto the upright, and the hub presses in. Shares the same part with non-turbo Z32s, so the fact that the used OEM 300z parts I bolted on 12 years ago are just now failing is pretty encouraging. Any experience with this type? Is one manufacturer of sufficiently superior quality to command a premium price? Judging by Rock Auto prices can range from $30 for an "economy" replacement to over $90 for a Timken branded "Standard Replacement" unit. Or just take a chance on another set of "used" factory units?
  5. Hi everybody. I've got a couple days to get rid of the E36 M3 that's shown below. I don't have a title or bill of sale. The owner recently moved to Washington, and abandoned the cars at my shop in Costa Mesa, CA. The price is 100% free, and the only catch is you have to come get it immediately. I am actively looking for a dismantler to come get this, so if you don't act fast, it may be gone quickly! Car was used as a street car previously. Most interior, glass, and harness pieces are still in place. Obviously the engine and trans are missing, as well as the front end. The *entire* rear suspension, diff, axle, etc assembly is all still installed as well. Car suffered a front end collision, but the rest the car is just fine. Thanks for your interest, Kirk Feldkamp Please call or email ASAP: kirk@urbanworkshop.net or 503.703.4869 (personal cell - please don't call past 8pm)

I am actively looking for a dismantler to come get this, so if you don't act fast, it may be gone quickly! This car was track prepped prior to being sidelined. Worst case, the cage looks good, and would save a new team a ton of effort. The rear suspension is still installed, but no diff, engine, or trans to speak of at this point. Front end is tweaked to the right a bit, but anyone with a frame rack could have this thing straightened out in no time.

  8. Hi Chumps, Looking to run a 97 Civic Ex. According to the rules, it is a 375pt car, which gives us some room to upgrade. I'm not 100% familiar with the rules yet, so I thought I would ask here. I'm a newbie, so please be patient. Questions: The car I'm looking to buy has some work done to it. It has a coilover kit and camber plates. Do these fall in the 2x rule? The car has an aftermarket exhaust. Are they allowed? What is the point penalty for adding a turbo kit? Thanks!
