What you all think?

As some of you know, the POS is no longer a street car, and is making the leap into dedicated drag car... Somewhat like Morgans car, the POS will remain a pancar, but now has a narrowed and lifted rear end, a built transaxle with spool and Dave Folts axles, a pie cut frame head and alloy beam... A cage is in the works too.... To drive all of this I'm building 2387 turbo charged stroker.... Not a big gun engine with bulk power, but enough to get into the 10's maybe.... 11's more likely.... The body is all steel, and always will be... But will be trimmed a little here and there.... Might go with plastic windows, and will have a light weight interior.

So I guess I'm saying the car will not be a light weight, will never be street driven.

I also have the luxury of a world class track at my doorstep, with plenty of slow down area..... Should I go with spindle mounts on the front, or stick with some form of brake on the front?... I still have the ercos I have been running for years, though I'm going wider on the rear, and I also have a pair of spindle mount front rims...

What do you all think?

I had to have brakes for AllMotor, and despite the weight, I really like them now.
It is very difficult to heat the tyres properly without them,
and you get the added bonus of a bit more braking.

That being said, there is probably a 100lbs saving going to spindle mounts.
Michael Nash's new ones have a PCD built into the hub for future rotor.

On my 2387 turbo race only car I was facing cars that were only a few tenths faster than me in heads up racing so I foolishly decided to lighten the car up by putting my Mitchell spindle mounts back on the car and removing my bigger rear disc brakes and installing some light weight units. When I finished replacing all that and removed my billet wheels and put my Mitchell wheels on the rear I had shaved over a hundred and twenty pounds, Et wise it was around a tenth faster. My first hard pass I ran a 6.37 1/8th mile pass but when I hit the brakes hard I sure missed the front and rear big discs , I missed the first turnoff and had to go to the second. Thank goodness for a long shut down lane . After you read this I bet you can guess I would stick with the 4 wheel brakes. Can you stop without them , sure unless something happens where you have to do a panic stop . This is only the opinion of an old man who has luckilly lived long enough to grow old . LOL , Mike McCarthy

With 2380 turbo I would run the front brakes, I'm running type3 rears only and at my top speed of 96mph they stop fine, any faster and they are going back on

Troy is running front and rear discs as well as shutes. If shutes fail he can still pull the car up if need be. Plus better burn out to get heat into rear tyres!!

It's a bit of a grey area Humpty. I ran a S/ST years ago with no rear brakes, which is now illegal. Nice to know I had some input into the rules!

Anyway, Superstreet and Super Sedan in the rulebook say all rules applicable to "Gas" class sedans apply. The rulebook is mainly referring to safety regs of course, not everything per se. Howeer, in general safety regs it says in 4.10.1 a minimum requirement of 2 wheel hydraulic brakes "on the rear", however, it also reads straight after that.........
"Four wheel hydraulic brakes are required on some vehicles as noted in class requirements. All Group Two sedans are required to have four wheel brakes as a minimum."
Group Two meaning "Gas" classes.

Bottom line is, at the 'Plex you can stop easily with only front brakes acting on 4" wide front runners from just over 130MPH, due to the uphill braking and long runoff.
Legalities, well, depends who you get on the day, but generally a token effort (eg, motorcycle discs and calipers for instance?) will be happily passed, whereas none at all is just asking for a rule determination on the day........

PS Hard to get tyres hot with a quick chirp, unless you're running "super-softs", which don't last. You need a few seconds, which needs front brakes.

I found front Brakes useful at both ends of the Dragstrip - at the start when using the line-lock to heat the rear tyres and at the finish line to help you make the turnoff road safely.
Is the time card worth the safety?

Thank you gentleman.... You have confirmed what I have been thinking all along.... But you know how options when presented with solid arguments, come along, the evil fairies on your shoulders start to bicker... This little chat has just put smarts before the red mist....

Brakes it is.

Might turn those spindle rims into a couple of nice workshop clocks.

I have drums on the front but only used them in the burnout.running 109mph rear drums were enough to pull me up safetly.
I used all 4 for the first time when i ran 118mph. Next run I ran 119mph and only used the rears again to see how it pulled up...... I will use all 4 from now on!!!!!
