Turner 4 Piston Calipers On The Car

**WLMS_F1** · 07-10-2003,08:31 AM

Hello Folks,

I am seriously considering the purchase of the Turner 4 piston calipers! But I'm not sure how the gold color will look on a red car. So, my question, does anybody have photos of the calipers on the car?

Thanks for your time everyone!

Why are you considering these calipers?

You may want to consider using the solid pins and bushings from Bimmerworld on the stock units. It will eliminate the twist of the stock units and create more even pad wear.

I am going to get a set if I decide to keep this car. I have never had a brake failure w/ the stock system and TOP QUALITY pads and fluids.

They are pretty sexy looking calipers though! But I am more of a function over form guy and I would spend the $ elsewhere on the car first.

My $.02 YMMV

oh cool! i just did my rear wheel bearings and noted how much flex was in the rubber bushings and thought to myself that that doesnt look terribly good for brake performance....

do the fronts have the same rubber bushings as the rear? i would imagine so.
i may just need two pair....

Point / Counterpoint...like how we may greatly differ in opinion on merits of the stock AFM?

I think the alloy calipers are pretty good. They fit under 15's and aren't that pricey. They weigh about 4 pounds apiece, saving around 7-8 pounds / corner of unsprung weight. And they subjectively feel very good - response / modulation wise. They appear to apply and release better than stock which leads to higher stopping force with reduced ABS action. Less grabby / more modulatable. They work well with the larger 7 series master cylinder some use on our cars, giving a nice firm pedal. One thing I'm keeeping an eye on is any wear along the side-of-brake-pad area of the caliper. As a steel backing plate touches anodized alloy in that area. Pricier calipers use stainless steel inserts in such wear spots. I'd like to play with an adjustable proportioning valve to get the front/rear bias tuned.

It would be nice to see an ABS upgrade for the car...the stock normal-E30 based unit is really showing it's age. It can't hack under 10 MPH very well (a street issue) and gets upset for a long time if one tire hits a pothole, turning the rest off briefly it appears. Like if you hit a bump when at the braking limit while autocrossing.

Many know that the 5-series of that era's hub can be used on E30 M3s to save bucks. You have to be sure to use the 3 series ABS ring, which has about 1/2 the number of "teeth" as the other piece. It would be worth a shot to use the 5 series ring on an E30 M3. That would go right onto the car. The challenge would be to get a different ring onto the rear halfshaft. I wonder if you could just use the 5 series ring and put a black box in the circuit to translate the signal...

Magnus,

You are the man! That's exactlly what I was looking for!

Trackman,

The car is a long term project car for me as well as my toy! In other words I plan to put money into the car regardless, so spend it now or spend it later!

:D

Stan,

You are always sooooooo thorough in your approach to vehicle engineering and I respect that totally.

Maybe though, w/ a $100 dollar upgrade, you can dramatically improve the existing calipers and have $ left over for pads too.

Speaking of PAds, it would seem that there are only a couple of pad choices to go w/ these calipers. If you are in my shoes, then those hawk blues are not what I want as the dust is just brutal on anything it comes in contact. Turner presently has no plans to get the HT-10 made for these custom calipers either so you are stuck w/ either HP-Plus or Blues for your pad choices

Unsprung weight is a factor but this is more critical on a bumpy road than the smoother race tracks. Then again, now that everyone is putting concrete through the corners, (LRP, WGI) this will start to be more important.

They are a very nice caliper. No question. Stronger too. But until the pad choices expand, I'd have to pass on these.

It is afterall, a custom built caliper soooo you may be out to lunch on pad choices forever.............

My$.02 YMMV

Eric,

Thanks, for the info on the pads! I changed my factory pads on my E46 because of the dust and went with the Hawk HPS-Black streets and a assumed the pads was available for the Turner calipers! I think I will hold off in that case, I hate fighting the dust on the wheels and with those calipers dust would not be good!

**Track man's M3** · 07-14-2003,08:56 AM

Glad I could help!

For the price they appear to be a great option. But that pad thing maybe a long term issue w/ these.

Get the bushing kit from James at Bimmerworld meanwhile. You maybe pleasantly surprised.......

On brake pads...

The KVR calipers are available for many different cars. They are not custom made for E30 M3s only. The custom part for our cars is the integrated mounting lugs allowing us to just bolt them on. You can see other vehicle applications using caliper on KVR's web site.

Any compound can be used with them, as you can have pads cut to size from wilwood blanks. I haven't tried it, but I think you can use dynalite pads as-is if you don't use the cross bolt. You'd have to use a retaining pin instead. This give up calper stiffness (hurts feel and modualtion..but lots of calipers have no reinforcement in this area). You could use the crossbolt with dynalite pads if you drilled a hole in the right spot. You can also save old backing plates and send them into many different places to have them apply their compound to them.

KVR pads have the corners furthest from the car's hub trimmed, and a cutout for the crossbolt. They made me some Ferodo DS2500 pads in a day or so and used dynalite pads for their blanks. They seem grippy although dusty but I am not using them at the moment as the brake bias is thrown off too much for best braking results in my tests (see other thread in the top topic forum)

Guys,

I emailed KVR to request info on there calipers, they replied back to me with price and how long it would take to ship. The KVR Python calipers for the M3 are $795 per pair and usually ship in 2-3 days. They also have a low dust carbon pads!

:D

Those are exactly the same as Turners but are red right?
Not a bad price. Think we could get a group buy going?

**WLMS_F1** · 07-14-2003,02:57 PM

Yup,

They're the ones, not sure about a group buy though! Anybody want to pursue it?

:D

**wookie1976** · 07-14-2003,03:42 PM

I might be interested in a group buy if we can get one going depending on the price. Any others interested?

**WilberM3** · 07-14-2003,08:49 PM

i'm interested in at least looking into a GB for them, although they'd probably still be out of my price range for the moment.
