Best M20 powered E30 lap time at Buttonwillow CW13

[Jean]

Well as a reference I was putting in consistent 1:59s all day yesterday and finally dipped into a 158.8 with my s54 car. Car pretty much has everything done to it under sun at this point. I think my limiting factor is wheel/tire size as I did this on 225/45 nt01s. 245/40s here I come lol

Awesome, were there any other e30s running similar to your times?

Will be looking forward to seeing progress with your new wheel/tire setup!

I mean, struts can be bent on track too :). Bending struts and clearancing strut towers is definitely common practice. Many people bend rear trailing arms also, to get settings where they want them without having to use rear adjusters that are constantly moving around. We don't have, and don't plan on having an rear adjustment in our race car until going to some sort of DTM replica setup later on.

I use to work for the Spec E30 record holder for the track we'll be at. Lets just say his car was very bent to his advantage.

I'm guessing they are bending their strut tubes/spindles? I can only get about 2.2* up front on my car with Spec E30 springs and GC Spec E30 plates before my spring perches bind on the strut tower.

That’s a helluva wager. Good luck to you sir.

Sub’d for results of said wager. :up:

Thanks, I'm pretty sure there will be some youtube video about it. I'll post the link after it comes out.

...I raise the question because I got in a bet with a friend to see who’s car could run a faster time. He will be driving a 1990 Honda EF with a stock d16, full interior, and a fully setup suspension. We will be running the same tires as Nitto is willing to supply us with tires. If I lose I committed to selling my car and buying a Honda. ...

Yeah but all of the fast spec e30's have plenty of camber. No one running up front with less than 3-3.5, most have over 4.

What suspension are you running thats better than the SpecE30?

...anything that lets you add front camber?
That's the SpecE30 Achillies' heel...

I'm always down! What day and organization are you running with?

December 3rd with extreme speed.

We're going to be using transponders from the track. I also use and AIM solo just for in car reference.



Spec e30 suspension is just H&R race springs, Bilstein shocks, and sway bars. I plan on running a complete Ground Control coilover kit with race camber plates, sway bars, and rear camber/toe adjustment plates. My friend is the Spec E30 record holder around that track and his main complaint is the spec suspension is too soft/too much body roll.



Congrats man! That's awesome. A wider tire will definitely make a difference. I'm shooting for a 2:05 with the M20. It's a bit optimistic but I think the temps will be more agreeable in December. You should come out.

I hope you are using the same lap timer and hardware. I'd also suggest getting a better GPS sensor if you are using something like Harry's on your phone. Those are too inaccurate to risk your e30 over.

Good luck.

If I lose I committed to selling my car and buying a Honda. I rather not sell my car so I’m trying to figure out how much suspension will need. I currently run a 2:00.14 in my E46 M3. All stock power and weight. Just suspension and tires.
