Suspension Pre-preg carbon bumper beams

[liftnot]

another lucky owner is getting one of these bolt on 3lb. carbon bumper beams made from prepreg. Losing 20lbs or 40lbs(both frt and rear)makes a big difference in handling. Comes with washer bottle mounts. $1250 ea. + shipping.
Feet in pix is over 250 lbs and the beam did not even make a noise.
working on 3D printed brackets but not ETA yet.

Thought you're running group buy or something.

Everything at P2F is made to order. Prepreg has a short shelf life and is too expensive to sit around. We could run a group buy say 5 or more but people need to be committed not just involved and disappear when its time to pay. Our first offering is usually the best price and we have two new product coming out.

Is this front and rear or just front for $1250?

Id be a commited buyer.

group buy price?

 

[liftnot]

Just the front. I want to make sure, these are not bling parts(u can't see them from outside, such a shame) and if you understand loosing 40lb at the ends can do to the car handling, then these are your kinda parts.

the rear cost the same. If we have more than 5 people sign up and prepaid, we can have a better price for the pair but most people want more hp. Lowering the PMI is not in the interests of many.
You need to PM us to sign up as our status is not vendor.

This one is sold. Making another set(frt & rear) for a new buyer. Takes 2 wks.

Had a few PMs:

>would you consider made it out of FRP so its cheaper?
If this car was a RSX, we would. Fiberglass was a high tech solution back in the '60-70s. We only use fiberglass for making surfboards. We want to make stuff for the NSX that is better, lighter, stronger than oem at least from material POV. You can certainly find less expensive oem alum bumpers but that is a lateral move and still at 15-16lbs(?). Carbon was high tech in the 90s but it is very common now especially cosmetic parts which this part is not. And most carbon parts are either RTM/infusion not prepreg which takes special skills. Price and value is not the same thing. If you can find a part that will loose 40lbs at the ends, made out of prepreg(or anywhere on the car) for this price, we will give you a discount and a trophy.

>is there a GB price for this part?
the best time to buy P2F parts is during the 1st, initial offering. From that point on, we get 1 and 2s request every so often and its not hard to have multiple people sign up but when its time to pay, most disappear.

>why don't you have the part in stock like other vendors ready to ship?
we maybe slow but we do ship. Prepreg need special care (see the 4C video https://www.youtube.com/watch?v=ewOD1YUUzX8). we don't have automation, we don't have an autoclave but the care and the skills are vastly different than wet layup. The shelf life of prepreg is short. The vendor we use is a long time friend from our IMSA GTP days. No other vendor is willing to make 1 or two parts.

Here is one article we get our inspiration from making better parts: at least we try.

Bashing such a fine machine, DC5 I mean using the strongest material is not always a good idea - especially talking about parts that suppose to absorb impact. Similar to say using stronger than necessary toe links and when on impact bending/cracking subframe beam. What would be the down side for having the same part in FPR? Realistically.

What do you mean by short shelf life?

 

[liftnot]

We are ready to make this part again as the vendor moved to a new location. $1250 each + shipping.

Here is some background info:

We like the 4C...working on to be our next car. The ability of prepreg, autoclave carbon parts are known for dispersing the KE upon impact since the John Watson crash in the 80s at 130-140mph. The energy is not absorbed and transferred to the chassis/suspension or worse, the occupant. This part will shatter upon impact as it should. Fiberglass for NSX?? FRP parts are not for impact/structure but they are popular and $$$. There is no price money for driving at 10/10 and beyond to risk crashing the car but to loose 40lbs at the ends to reduce the PMI is a welcome upgrade/tradeoff(than the oem steel bumper) we are willing to take. The method this parts is made is similar to a typical race car and with foam inside. But, if you don't feel safe about it(since we have no crash data), this part is not for you. We rather loose 40 lbs and know the limit of our ability than not to have one.

Since the 50s til now, many/most race cars are built from steel tubing and upon impact especially on a road course or oval, the tubes will bend and crush the driver. drag race is less likely receiving side impact but when it does(like the Atlanta raceway death last wk), the end results is not pretty.

We have used alum toe links with no steel inserts for threads and it lasted less than 1.5 yrs. on the street not being a daily. Alignment settings were not able to stay put. Now we have 4130 toe links its much safer. If you are worry about damage/cracking the subframe, than stay away from wheel to wheel racing and do track days to stay within your limit. Spare parts for repair is scarce to none.

What do you mean by short shelf life?

short answer: raw prepreg has a short shelf life as it must be stored in a cold condition to slow down the cure cycle of the resin that is imbedded in the cloth. Thus the cost to make a part is also higher than regular carbon cloth.
