Update by J.G. Pasterjak to the BMW 435i project car
Mar 13, 2024 | BMW, SCCA, Time Trials, Project car, 435i

One of our hopes for our BMW 435i project is not just to build a fun, track-capable car, but to build a car that can actually compete in the Sport division of the SCCA’s Time Trials program.

The Sport division has its philosophy rooted deeply in “dual-duty” enthusiast culture, and the prep rules are structured around building a car …

Personally, I'm going to enjoy seeing how much more time we can shed as this project progresses.

I also think it's interesting/cool/weird that we live in a time in which you can plug something into your car and just add more power

I really do appreciate, these set ups, as I am always curious if the old guard can keep up with the new fast models out there.   I myself am trying to run autocross against the mighty ND mx5 with a 2006 z4 3.0si because on paper it really looks like it has a chance.

But please do me a favor an put the right tires on that bimmer, otherwise its a waste of an afternoon.

So this baseline was before the K-brand shocks, Vorshlag camber plates, and the 200TW tire upgrade? That right there should make a MASSIVE increase in cornering speeds over the non-camber 540 TW all seasons. Excited to see the next phase of testing, keep it up!

As I have mentioned to JG several times, this this is going to easily run past my M3, right?

Oh yeah this was straight off the used car lot.

Love seeing Terry Fair up in here.

I bought Vorschlag camber plates for an E36 M3 back in 2006. They were phenomenal! And customer service was amazing. I remember when I couldn't get enough caster, I called and you helped me figure out I simply had the Ground Control struts I'd bought mounted on the wrong sides. cheeky

Glad you're still up and running!

Love seeing Terry here as well. 

I rode in the 435i yesterday. It’s now on Vorshlag camber plates. I don’t want to give away anything, but you don’t hear a peep from them. (I know, I’ve said too much.)

So I probably missed it in the article but was the GR Corolla tuned to the limit of the class or was it also basically stock but only had better tires?

Data logging has taken all the bench racing and arguments from said bench racing when the track goes cold and the beer comes out.  ;-) I mean my but dyno is obviously better than your but dyno.  (Yes this was actually said at one point when a track went cold and we were all sitting around)

The GR Corolla was a new car test, so it was run as delivered. 

You'll need to log in to post.
