210's UNITE!!!!!!!!!

Put drilled and slotted rotors on. Seems like adequate brakes for the stock A15 haha

When it comes to brakes, I prefer "overkill" to "adequate".  😁

 

The real issue is fade. Those brakes will stop the car great, until you try to do it 2 or 3 time in a row. Then you might want something beefier. 👍

They still sell drilled rotors???

 

Looks like the 210 used the same calipers and rotors as the first gen 200sx. The 200sx weighed about 2,300 pounds to the lighter 1,900 pound 210 so the 210 should outbreak the earlier car.

 

Takes quite a bit to get them hot enough to fade but very scary when your brake pedal goes to the floor and nothing happens.  The rotor is a thermal heat sink that will absorb any panic stop, then disperse the heat over time. Unlikely you will encounter multiple panic stops in a row in normal driving. I guess the 210 didn't come with vented rotors. 

 

You might get better results with a more aggressive pad compound but they tend to wear the rotors faster. Ultimately your braking performance comes down to the tire size contacting the pavement. 300zx brakes won't stop you faster on skinny tires.

I replaced the brake pads with Dynamic Friction ceramic pads. Those were the "best" pads on rockauto for whatever thats worth haha Tires are 185/60R14. New wheel cylinders in the rear. The drums look good, but I'll probably replace the shoes this winter. The new master cylinder comes in today, so I'll be replacing that and the front soft lines that connect to the caliper hard lines. Everything combined should hopefully work pretty good.

Who said "normal driving"?  😁

Until the mid 80s, everything came with solid rotors except some of the 6 cylinder cars (280ZX, Maxima, etc).

Hey there fellow 210 fellas! I'm looking to get an '81 B310 so I can put the 5-speed (and maybe the A/C equipment) in my '75 B-210 coupe, but now I'm curious about doing a little street ripper on the B310. Does 510 rear suspension really just bolt into the B310? I see in the service manual that it uses coil springs and multilink (upgrade from my leaf springs!) buy I'm not 100% sure. If it does, I see the T3 rear coilovers for 510 and they look pretty slick.

Seeking advice and knowledge! Thanks a bunch.

 

Edit: I'm not worried about front suspension, as 280ZX coilovers bolted into my B-210, no doubt they'll fit in the B310.

Poor wording

[datzenmike]

The 510 IRS does not just 'bolt into' a 210 and why would you want it???? It has it's own faults. Stick with what you have.

 

I also doubt that zx front coils fit the 210 or the B-210 strut towers. They are too wide. The zx struts can fit and just use the 210 coils.

 

You need to do more research on this.

[ToastyBass]

Datzenmike, I'm sorry, idk what to tell you, but my '75 B-210 has 280ZX coilovers & brakes on the front, they work great, stops on a dime. Pretty sure they're the complete T3 assembly (sucks bc you can only adjust the spring seat, basically like cutting springs)

 

I apologize for not being more specific.

Looking through a service manual, I noticed the B310 changed to using coil springs & multilink on the solid rear axle, an upgrade from my leaf springs. When I was asking about 510 compatibilities, I was referring to using 510 coilovers on the solid axle in place, not converting to IRS. That alone sounds like a nightmare I don't want to deal with unless I was making a whole tube chassis from scratch.

[datzenmike]

Coilovers yes but not zx coils.

 

Yes the zx calipers and vented rotors are a great up grade on any Datsun. I have Maxima front struts with larger calipers and they are vented rotors also. The Maxima is a large heavy car at 3,100 or close to 1,000 pounds more than your 210 and 300-400 pounds more than my 710.

Sorry I didn't differentiate coilovers from coil springs! My b!.......{210}

Anywho, thoughts on possibly using 510 coilovers in a B310?

 

The shock absorber dimensions look very comparable to each other, but the 510 does have heavier springs. (yes, I know it's the factory suspension but I'd assume that any coilovers, unless stated otherwise, would closely mimic the factory specs to imitate factory ride if not improve it)

 

Here's the set I'm looking at rn:

Silver Mine Motors COILOVER SUSPENSION KIT FOR DATSUN 510 1968-1973 with 30 STEP DAMPER COILOVERS NISSAN COUPE OR 4 DOORS (DOES NOT FIT STATION WAGON)

[datzenmike]

The coil over is basically a shock absorber with an adjustable coil on it. Any thing that matches the 210 rear shock for length and mounting will do, doesn't have to be for a 510. (they are probably more expensive just because they are for 510) Just like the Maxima struts and brakes are about the same as the zx but wrecking yards give them away. But if you say they are zx the price goes up because they are collectible.

 

'84 Maxima station wagon struts I got for nothing.

I don't know if the shock will fit or not but don't plan to keep the coil spring on it without some added bracing to the shock mounts on the top and bottom.
