Default Geometry Correcting Spindle

I thought you guys would like to check out these trick race parts. Brian from Midwest Eurosport made these for me to correct my bump steer issue while strengthening the weak points in the spindle. These were fabricated using my parts. He has made several of these style parts in the past and has been supporting (and racing) 944 platforms for over 15 years.

Price was $800 and are custom made for my application.

Those for a Fabcar, Charlie, or RE arm spherical bearing?

These are for the Racers Edge A Arms. He has made several for Fabcar and can do the Charlie Arm.

Looks very solid, what about drop drop spindles, does anyone make this.? You would still have to use a longer tie end pins to get correct geometry with these.

Did you think about having the steering linkage arm moved too? To eliminate bumpsteer?

Eurosport definitely does good work.

I was equally as impressed with Brian's trans cooler setup on his S2. I wish I took pictures the last time I saw it, I'd love to do something similar for my car.

We are using the Elephant racing bump steer correction part for the steering control drop.

Eurosport made the entire part. It integrates the greater pin length to my specification. We modified/increased the pin length by 1.5".

I met Brian after he and his crew were seen crawling under and over my car while at a PCA race weekend, they liked the "unique" modifications. Brian impressed me and my mechanic (Eniac) with a number of solutions to 944/951/S2 common problems. They support several race cars and show up with a full crew of personnel and transporter. Great guys.

Not that I have any mechanical basis for what I'm about to say... but I have this issue of welding on those. The thought of them breaking under full load at 170mph on a high bank is too much to stomach.

Again... it's a total mental thing. I actually bought a new set "just because" on my previous red car. I really worried about the load on those (stock unmodified spindles) with 315's and real high g loads.

Very cool though and certainly solves a problem.

I agree it's not a perfect solution but it is superior to the common alternative of a lengthened, unsupported pin clamped by bending a cast component.

I'm sure it will be fine. However it wouldn't hurt to take them off after a full track event and have them magnafluxed just for piece of mind :-)

No f'in way. No disrespect but no way I would use those.

Disregarding the question of the welds, it would be interesting to see this piece and the stock piece side by side? I currently have R/Edge arms with the longer pins and Elephant Bump steer kit. Haven't driven on this combination in total but would be interested in an alternative to the pins.

Everybody has to make their own decisions. This spindle is built with the RE pin.

The stock 951 spindle is an inherently bad design for seriously fast race cars. Large front slicks provide enough grip to spread/bend the spindle arms. Dwayne/Kokeln/Vision discovered this with Orca, hence the 911 front suspension components.

Continuous bending is not a good thing for cast parts whether this occurs through threshold braking or clamping of the pin. The only other solution to solve the front wheel situation is to go the route that Tony G. has taken (Dwayne/Kokeln/Vision method - 911 parts).

Everyone has to make their own decisions on race fabrication. My decisions are based on personal experience and of course, several race engineers I have come to know and respect.
