I have a 951 where i want to upgrade my brakes next winter.

It has the early suspension in front where the disc are in-between the wheel bearing.

And my Azeva wheels just fit under my fenders, what is the offset difference between early and late suspension?

If I’m changing to late I also need to buy KW / HR coilovers.

Or do I just go in CAD and make a new bell with AP disc`s ?
I’m going with the Bigblack 996 calipers and 330x32mm disc in front and 324x24mm in the rear and 996 rear calipers.


Sorry for bad writing, too early in the morning in Norway atm..

Thanks for all the help coming, i really appreciate this forum

About 30 mm...early offset is 23.3 mm and late offset is 52-55 mm, depending on the wheel.

If you search around [race shops], you should be able to find several options for adapter brackets that mount Big Red/Black calipers to both early and late turbo spindles.

Is there any other performace benefits to change to late suspension?

Brackets are no problem, im after senterbells and brake disc.

mel_t_vin

Not sure what you mean by senterbells...hubs?

IF you are having a tough time squeezing your wheels under the fenders now, with an early offset suspension, THEN changing to a late offset suspension is only going to make matters worse.

In other words, if your wheels need an additional 10 mm offset now, they will need an additional ~40 mm with a late offset suspension.

Yes the Hubs, Sorry english.

Wheels i Can buy new, but is there any "must have" on the late suspension?

mel_t_vin

What do you mean by must have...from what perspective?

What are all the parts you must have to properly convert from early to late offset suspension?

Im planing on big black 996 calipers, And 330x34mm disc.

Is the newer spindle And wheel bearing more solid than mine?

Can the newer use 996 discs, or do i need new hubs for the disc?

Sorry if My sentence buildup is bad.

Can't help you with fitment of 996 parts on a 944...have never even given it a moment of thought.

Unless you are racing, on the track, and require a larger mass for heat dissipation, there will be no performance gain from a BBK on a street-driven, canyon-carving, 944 turbo...I can put you through the windshield of my car, at will. There is absolutely nothing wrong with those baby black calipers, 99% of the time.

Are you going for aesthetics, or bragging rights...or you just have a couple thousand Euros burning a hole in your pocket? Now, if you just want a BBK on your car, no argument from me...your car.

Suggest you wander over to the 944 turbo forum...there are plenty of guys over there that can't help themselves from making constant, continuous, improvements to an off-the-shelf chassis Porsche sent to countless race tracks around the world. Someone over in that forum has undoubtedly gone down this rabbit hole with various levels of results/success. Best of luck.

And don't worry, your English is fine.

No bragging parts, just needed uppgrades Next winter

My brakes faded last year on track in a downhill Where we brake from 215 km/h to 110.

Therefore My question

mel_t_vin

Were you using good fluid? Have appropriate pads installed for the track? And ensure adequate airflow to/through the rotors?

ealoken

Gulf racing brake fluid
Ducting And EBC NDX brake pads.

Im rebuilding the ducting, braided lines and new disc's this year

If you want to keep early offset but want an easier path to a BBK, you can run late hubs and spindles on early suspension. The offset difference comes from the a-arm.

This is the setup I run. Aside from the work to replace the spindle/hub, it keeps everything else much simpler because you can use more standard off the shelf parts from caliper adapters all the way to rotors.

Thanks, what disc's do you use?

I'm running two piece rotors: factory rotor with a Lindsay racing hat. It's been years so I don't remember well, but I think they are 993TT rotors.
