Best M20 powered E30 lap time at Buttonwillow CW13

A lot of factors at play here but Toyo RR's are not significantly faster than DOT-R's, so I will say yes (without any knowledge of the track).

That’s good to know. I haven’t driven on RRs around a track so I’m not too familiar with their grip level. Thank you!

I think you would at least need a s52 to get into that territory but I could be wrong.

My Co-worker with about 6 track days under his belt is running 2:08s now with 2:06 showing on the predictive laptime. He ends up running into traffic since he runs in an intermediate group. His car is completely stock M20 powered with Bilstein sport shocks (stock housings)and a Ground Control coil over conversion. Tires are Achilles ATR-K (140 Treadwear). Spring rate is only around 350lbs. 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. 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.

Like the title states, anyone know the best lap time a M20 powered E30 can do around Buttonwillow CW13? I know the Spec E30 record is in the 2:04s. I’m curious if a street car with a relatively stock engine on DOT-Rs and better suspension could run faster than a 2:04?
