Sports Pkg questions

[papashango]

1) Is the ride stiffer than base due to the rim/tire difference?
2) Is there more/less road noise than base?
3) What difference could you feel on the street with the LSD, if any ?
4) Does anyone have the 60-0 numbers on non sports brakes? I think it is 101 for the sport brakes.
5) Would the sport brakes last any longer or shorter than base brakes? Would they be a lot costlier to replace?

Thanks!

I only drove a sport. I assume that the suspension is a little mor stiff and you can get both rear wheels spinning due to the LSD.. no one wheeler peelers here..

[papashango]

I dont think the suspension is any different, but i imagine 19" rims = thinner tires = noisier/rougher ride?

[christian370z]

The difference in ride quality between the base 18s and the 19s would be marginal to be honest, I drove the base and S/P Z and they felt the same. As for the LSD: it depends on what you may define as street driving. In the canyons, I feel like having even the stock LSD is a HUGE advantage over open diffs like my Touring. Coming out of turns, I can tell the sport package cars get much better corner exit speed since their inside tire does not spin and waste power.

In casual day to day driving, little to no difference with the limited slip.

1. The ride might be slightly different. The taller sidewall on the 18's will soak up a little more of the bumps.

2. The sport will have fractionally more road noise due to the wider tires.

3. In street driving the stock LSD will lock up and help get the power down but mostly is only of benefit in situations where you would have the VDC off. In cruise mode you're not likely to notice that much of a difference.

4. I don't think there was much in it, maybe 2 feet.

5. The sport brakes are more likely to wear evenly vs the floating caliper design. Pad wear overall is more of a driver factor. Replacement parts are going to cost about the same with the exception of the caliper itself which are usually good for 100,000 miles before needing a rebuild.

Maybe only 2ft different from the sport brakes to the stock??? You know the rear brakes on the Sport are bigger then the front brakes on the base? Not to mention the 4 piston calipers.

Brake rotor size isn't really a determining factor in stopping distance (for a single emergency stop), if the brakes are powerful enough to lock the tire and activate ABS then they will get the job done in equal fashion. Repeated application is a whole different story, and one that isn't typically told by these kinds of test.

The braking distance in these 60-0 tests is basically a factor of tire size and efficiency of the ABS brake force distribution.

again. I do turn VDC off in these situations.

[papashango]

Chris, so you think the stopping distance between base and sport brakes is not much? only a few feet if i understood correctly?

[kenchan]

if your car's going to be street driven the base will do just fine but the sport package just finishes it up for you from the get go.

as for the stiffer ride, put some wheel spacers on and soften by wheel rate. it's a pretty comfy ride. (15mm rear 20mm front is wat i use). i use 37psi in my RE050A tires.

GL!

The biggest difference in the brakes won't be stopping distance. It will be how much abuse the sport brakes can take over the base. They'll stop over and over with less brake fade.

Parts Needed (Upgrading from base Brakes to Sports?)

--------------------------------------------------------------------------------

What Parts are needed when Upgrading anybody??

I Bought
1. Rotors
2. Brake Calipers
3. Brake Pads

anything missing for my tech??

I had base Brakes and im upgrading to Sports package Brakes
370z ?????

[ChrisSlicks]

Sport brake lines (stock or aftermarket SS).

[sonic370]

for the 3 grand extra for the sports package it's money well spent.

if you bought after market for all the parts mainly the wheels,tires and bigger
brakes that's easy an extra 4 to 5 grand there.

jmho the base z is just what it says it is BASE. but if your a tuner and won't to add all the extras yourself start with the base.

sports package is a great deal, as long as your happy with the parts it comes with. It's actually easier if you plan on upgrading parts sometimes since people without the Sports Package usually buy up the used parts.

To upgrade a Z without the sport package, you would need:
LSD: about $1,300 (true LSD, not VLSD)
Brakes: $1,800
Aero: $800
Wheels: $1,200 (used)
No SycroRev

On the upside if you get a base. No holes to worry about if you want an aftermarket wing. Technically less to upgrade the LSD (no stubs axle flange req.). Most importantly, it's gonna cost you less to buy the car in the first place. The way I saw it, I had a choice between base with sport or base with touring. Having both was out of my budget at the time. I figured the sport package stuff would be easier to upgrade in the future than upgrading the base interior to the touring package. Its not like your gonna enjoy the car any less.
