I can't find anything using Google. Looking for any feedback/opinions on the DM10 please. I have a ChaseCam and am looking for data and don't need a dash. Seems like the most cost effective/simplest solution for my situation. Anyone tried the DM10 or know someone who did?

I know they are not DOT legal and are not IT legal. I think Hoosier is at PRI now so trying here. Can't find much on Google, anyone able to give any info/feedback on these? Grand Am radial wets, hand grooved. What compound is this shaved from? How different are they from say the DOT...

Need 4 new tires 205/50/15 (no rims) from Oklahoma City, OK 73106 to Dallas, TX area. Seller doesn't want to ship, I don't really want to make the drive. Anyone travelling that route in the next 2 weeks or so? Payment already handled with seller. $50 for gas? Thanks

Disclaimer: I have no affilliation. A formula car buddy is really into lap records and asked if I would help spread the word about www.laprecords.com I on the other hand could care less about lap records even though I hold some in SCCA SOWDIV but they never update the information and with NASA...

What's the proper procedure since putting 1000 miles on it under 4k RPM is not realistic? New rotor bearings, among many other internal parts, not to mention a new ECU with only a base map. Do I start it, run for 30 mins at low idle, change oil, idle under 4k RPM all day outside the shop and...

I got it from an ex-Speedsource car and was not sure who made it. It looks like an RB to me but is not stamped as such. What headers did Speedsource use? Did they make their own? The Speedsource car this came from now runs an LS2. Thanks.

Anyone have this issue? I flush my fluid after each weekend. Never have an issue with the rears but just busted both right and left bleeder screws on the fronts again. The calipers on the car are less than 6 months old and have 3 weekends on them. Both bleeder screws snapped and it's happened...

I had my suspension all apart and ended up selling my RB front strut bar for no particular good reason. I was going to get the AWR strut bar now then realized Mazdaspeed had one but can't find a picture of it? Is the AWR one the best out there or? I don't like the way it's promoted "...

Last I spoke to Mike he didn't have any more front sections and didn't plan on making more. He did say if there was enough interest, he would do it. Anyone interested in one? The front section is the part that bolts to the header and has the expansion chamber. They are $225 normally...

As you know, the OEM driveshaft has non-replaceable U-joints. Is anyone using the OEM equivalent RX-7 Mazdatrix replacement? I know it probably works fine for street cars but have heard conflicting information for high speed racing applications. Thanks.

I spent an hour at the hot rod shop today trying to get a fitting like the one below. I have the fitting right now in -10AN 90 degree to 18x1.5mm and it's marked "Earls". The fitting I have is failing and starting to leak for some reason. Unfortunately the only ones in Earls catalog now are AN...

I have been using Hawk blues front and rear with no bias adjuster, have been happy with the setup. I got a recommendation to try the DTC-60 on the front and either the same on the rear or the HT-10. I've been told these last longer, are not as abrasive, and should brake better. Has any tried...

Is there any difference between the 89-93 and 94-97 Miata transmissions? Is the gearing the same? I know nothing about Miatas, only RX-7's. Thanks!

As the title implies, is there such a thing? I have an Aeromotive FPR under the hood but if I could control fuel pressure from the drivers seat that would be ideal. I can't find such a device... is that because none such exists?

Do I need this functioning? The connector is old and tired and the sensor has a terminal about broken off. Not even sure if it is functioning but when I pulled my front cover today (and water pump) it got even more jacked up. Was hoping it wasn't really that important, I am running a stock ECU...

Is this common? My last set of tires and current set both have slipped on the rim. More specifically, I use a tire crayon and mark the tire and the wheel, usually where the valve stem is. I notice the rear tires actually slip on the rim and rotate a few inches. Tires are Hoosier R6 225/45/15 on...

Are these prone to going out? I noticed ISC sells rebuilt ones. Mine appear fine to me but I do not know the history, heck they could be 22 years old. The boots are not torn either. I have the hubs off right now as I just changed the rear wheel bearings. Before I put it back together I started...

I have some sticker Hoosiers I'm running next weekend, unfortunately I just can't figure out a way that I'm going to be able to get that first cycle on them, and have time for them to cure. I do want try and maximize tire life. So, I thought of another idea and emailed Hoosier... On your first...

Any brake experts able to offer some advice? Is there any negative effects to remove pad brand A and put on a used set of pad brand B? I'm wondering if 1) the rotor should be turned, and 2) if used pads with plenty of life left are fine vs. new pads.

... according to Fuel Safe it is, here is the press release (it's a Fuel Safe PR, just happens to be hosted on NASA site) http://www.nasaproracing.com/norcal/events/fuelsafe2.pdf I would imagine same holds true for ATL but have not seen anything yet. Edit: Correction, maybe not such an...
