What is going to be your first mod?

Exhaust, the stock one sounds horrible in person.

If your car rolls over and your roof collapses.... you aren't moving an inch with a 4 point harness, and your neck/head/spine could be severely injured.
So it seems like it would be better to run stock safety restraints until/unless you install a roll cage, in which case a racing harness would definitely be safer.

I'm not trying to tell you what to do or anything, I'm just sharing information that I have been told so that you might be aware of any possible dangers. If I'm mistaken, feel free to correct me.

You are 100% correct. Racing harnesses were not designed for street cars. They were designed for cars with racing seats, roll cages, and drivers with helmets and neck braces or HANS type head restraints. If they were safer than they would be used in street cars.

This couldn't be farther from the truth. Stock seatbelts are designed to work with all of the other safety features in your car. Racing harnesses are more likely to be the cause of injury than anything else unless you have all of the proper safety equipment to go along with it. You need a roll bar, proper seats, a helmet, and some sort of neck brace/restraint before racing harnesses can be fully effective. Not to mention they have to be mounted properly at the correct angles. They were never designed for street cars, and street cars were never designed for racing harnesses.

Example: Front end collision. Stock belts let you move forward quite a bit, into your airbag. Racing harnesses don't let you move near as much so the majority of your forward momentum is absorbed by your neck. This means that the stress put on your neck and your brain smashing into the front of your skull is FAR greater than with stock belts. Again, racing harnesses are designed for race cars with race drivers wearing helmets and neck protection.

That's what I was trying to express, thanks for explaining more clearly

And to add to that, if harnesses were safer than normal restraints.. why wouldn't they be in normal street cars. The seat belts/ tensioners/ seats/ head rests/ everything in the car is designed to work together to have a synergistic affect and increase safety.

CAI and Cat-back on the first day I do any mods at all. (Probably within the first 2 weeks)

Mr. BigHam · 12-30-2008, 01:18 AM

I will deff. be buying my first mod from Cobb.

370zForever · 09-23-2009, 08:08 PM

Hold on, why is it necessary to get roll cages and roll bars with the seats and harnesses...Putting in a lightweight seat and harnesses doesn't mean that you will increase your chances to roll or get into a crash. The safety stuff (except the side airbags) remain basically the same..Right?

DropTopGal · 09-23-2009, 11:41 PM

Within the first week of ownership of the Z Roadster, my first mod will be a combo of several things.
1. Exhaust (likely the FI)
2. The rear light thingy.
3. A few LCD interior lighting changes and additions.
4. Hardwire the V1.
5. Maybe an intake, not sure yet if it is worth it.
6. A few other small things, but you'll have to wait to see it ;-)~

Oh, yes, the window tint...lol

The stock 3-point belts are designed to allow your body to bend and twist out of the way in the event of the roof caving in. With harnesses, this is not possible so the only thing that will be able to bend and twist is your neck...which can't take much bending and twisting

. Its the harnesses themselves which shouldn't be run on the street, not necessarily the seats. With that being said, most racing buckets will not let you properly use the stock safety belts either rendering them useless. So its a viscious cycle. Switching to reclineable racing seats without harnesses or a roll bar is usually fine though as they don't have the high side bolsters so they allow the stock belt to sit properly across your lap.

1. Giant Time capsule to keep 370z pristine forever.

Well..

1. Intake - done!

2. Suspension - working on it

3. Exhaust - Saving for it

ZeeRay · 09-26-2009, 07:10 PM

Well let's see first I'll install an ashtray! Then probably mufflers. Not a real fan of how the car sounds.

Nick911sc · 09-26-2009, 10:45 PM

Exhaust, intake, sways...Not exactly sure when though...Could be awhile
