No, they are 225's.

I believe the spring rates are published when you buy them, but possibly in a metric format. One thing I noticed in the pictures above regarding the rear spring set up. If this picture was taken with the tire in full droop, I'd say there is a good chance of coil bind. If you are in a corner or just accelerating hard and the coils all touch each other, essentially you have gone to what I call "infinity" spring rate. This will cause massive oversteer or lack of grip. greg ira

Hey Classic Z'ers, I felt terrible about not sharing what turned out to be one of the coolest Z cars I've ever seen. Even Pete B. really likes it, in fact at a vintage race at Sebring he commented that it's "one of the best prepared Z's he's seen." He really likes the color combination that generated the title of Executive BRE car. I couldn't figure out how to best share this build, BUT I had created a book for the customer on My Publisher. So, I just figured out how to share this with you guys. Take a few minutes to cut and paste this link, turn the pages, and read the narrative. All the best, Greg Ira http://www.mypublisher.com/?e=OHm3Q8zJl3T4ptMr7jMQ0R7sNng_WO78

Here is my latest customer build. What a beautiful car this turned out to be.

Does anyone know anything about this company? I have purchased stuff from them before but now they're either not answering my phone calls, or hanging up. Greg Ira

Hi, Is anyone a 240 SX rear brake caliper expert? Here's the deal. I am building a new race car and I am using this caliper. I am not using a handbrake and got rid of all the related parts. Aftern a couple hours trying to find out where this system was leaking I had the entire assembly submerged in water and was shooting air through it. Lo and behold, there is a factory pinhole in the grove of the piston!! Yes, the only thing to cover this hole from all the pressurized fluid is the flimsy dust boot that rides in that groove. Is anyone familiar with this and is this right? Thank you, Greg

Brubaker, You've probably determined it's a 3.7. That's actually the easiest one they make to divide out. That ratio came in the 79 280ZX and all the 300ZX's. Your picture shows non LSD. Greg Ira

Darn, I'll be in Sebring. I really want to start coming and getting involved with the SFZCC. Hey, if you guys are up to it, we'll be in Homestead racing the following weekend, the 14th and 15th. It would be cool to get some Z's down there. Greg Ira

Justin, Welcome to Classic Z Cars. For the tires to look "tucked in", you are more than likely going to need to section an inch or two out of your struts to keep from possibly bottoming the shock or coil bind. You will also need some sort of bumpsteer adjustment because the geometry in the front related to the steering rack gets whacky when the car gets real low. I would say the Tokico and Eibach route is a good one but it doesn't seem to get you as low as you want. Greg

I am working on this disc conversion. The SX brake caliper uses a banjo type fitting for the brake line, not a 10x1.0 inverted flare. Does anyone know a source of the brake line I'll need to complete this upgrade? Greg

Double Snap! I know they make real race pads at Porterfield. Thanks Blue. Greg

I am looking for any race brake pad manufacturer that makes racing brake pads for the Toyota 4 pistion brake caliper that goes with the "Stock Solid 240z' Rotor. I believe this caliper is from a 1979-1983 4x4 truck. It is not used with a vented rotor. Any advice is greatly appreciated. Greg

Does anyone have a specific point of contact with this company that knows about car parts? I hate calling into their call center and getting people that don't know an MG from a Z car. I noticed they don't have an email address on their website either.. Thanks, Greg Ira

Exactly what my next try is going to be. Thanks for the good information. Greg

Great answers you guys. I really appreciate it. Two things, I am using Lexan which is really tough to work with, and i run a total loss electrical system just for the extra tiney bit of horsepower. The good thing about the stock squirrel cage fan is it move a LOT of air and I think this alone will be very helpful. thanks again. Greg

Hello, I am attempting to build a defroster of sorts for my race car. I am never going to lose a race again because I can't see. I have a squirrel cage fan unit from a stock 240Z and noticed a little electrified wire coil on the exit side of the fan. Does anyone know what this is? Could it aid in pre-heating/drying the air? Greg Ira

Yeah, the dash is out of the car on a work bench. There are many areas where the dash cover doesn't touch the original, but it is a nice mold and sort of what I expected to have to work with. Lots of adjusting, banding, and gluing...

I am installing a full dash cover on a 240 Z and was wondering if anyone has some pointers. For example, the cover gets in the way of the glove box opening and closing. What to do? Greg Ira

Hello, Does anyone know if this company is still thriving, working, needing business, kicking butt, etc.? thank you, Greg Ira

Yes, the weather is terrible up there. Of my four visits, I have raced two of them in the rain. Brakke sandbags and as long as he's the head of the comp board and is at his home track, he'll have the advantage. Take him away from his element and he's not that good. In the rain he's terrible, I lapped him. That felt great. Thanks for keeping up. We'll be faster next year. Greg Ira

A certain amount of whining is normal, but the cars didn't come from the factory with the level I think you are describing, therefore it's in the rubber isolators and the perfect set up of the differential. The set up is a little tricky. The ring and pinion gears are matched at the factory based on their wipe pattern. They do wear and you may be able to slightly adjust the backlash between the two gears. A possible difference in the noise when under power or not is in one instance the pinion gear is driving and in the other the ring gear is driving the unit. I have used many junkyard units with minimal noise. I use them for racing and they are pretty durable units. The sound is more than likely creating heat too but I have used these before with very loud noises in some situations. Greg Ira

Classic Z'ers, Firstly, congrats to John Thomas for smoking everyone again, and to all the other Z drivers at the solo championships. As usual, I want to invite anyone interested in the best road racing america has to offer, to come visit us and our team at Road America. We will be competing in E production for the national championship against a large field of which there are probably ten different drivers that can win. We will be up there from September 16-25. If anyone wants to come out, just let me know. Thanks, Greg Ira

Phillip, I do have a 1.8 first gear and starting off through the paddock is tricky. I never rev the engine up high to get going and I don't hear the dogs raising hell. Since I have a 5.5 inch clutch, I have to be as nice to it as I can. I rev it just enough to get the car to roll, then I let the revs way down and let the clutch out quickly, not much stress on the clutch itself. In my case where we are penalized weight to use the dog ring gears, it seems to be better to go lighter. 108 lbs is a ton in a car that weighs 1990 lbs. When we go up to test before the Runoffs, I have the car and team set up to do a back to back test with the set ups. Whatever we run will be the best set up. I am predicting the stock set up will be better. Don't forget about the fewer shifts per lap too. Lemme know how your guaranteed 2 secs turns out. I am very curious about this. See you, Greg

Hi Lowell, We will be at Road America again this year with a lighter more powerful car. We are also using the newer Hoosier radials, which is a sharp contrast to what has been used for many years. Anyway, I think we still have a decent shot at a win. We just need a little bit of luck. Greg

I believe it's completely achievable to get 260 hp out of a CP engine build. We already do it. Also, I don't think the 2.4 liter Porsche is in the CP class according to the rules in SVRA. That's a good thing because they make tons of power and can get down to weight which is very hard for the Z. The Z is CP trim must weigh 1968 lbs. Try to get there. It's probably best to take the penalty and the brake upgrades. I have found that there's a lot of tolerance at these event because they like the numbers, BUT-UNTIL-WAIT, don't beat the Porsches. Oh my, once you start beating these guys, all heck breaks loose and you might as well put you car in the hauler because about ten rich guys will be crawling under it. It happens to me almost every time I go race against them. People in general, except Z enthusiasts, have forgotten how fast a well prepared and well driven Z car is..... Go get em!! Greg Ira
