ROW M030 suspension stiff enough for slicks?
Long story short, im planning to run autoX and DE events next season on slicks.
Is this ROW M030 stiff enough? I really want to avoid buying the whole kit, getting a slight improvement, and then having to buy a full coilover setup. |
How experienced are you at track driving?

Gentle suggestion to consider a more forgiving track tire.
Racing Slicks do offer the highest grip level within a very narrow performance window and heat cycle out after 1-2 days. That means a fresh set of $1500 tires every weekend. One big spin and they go straight to the dumpster. :eek: They will also likely overpower your M030 suspension and you will need about -3 degrees of negative camber F/R. If you are pursuing a National Championship this might makes sense. For local DE/AX not so much. Other choices with excellent grip and heat characteristics but last much longer: RA-1s- Good for about 50 HC or 10 days. NT-01s- Good for about 50hc or 10 days. MPSC- Good for about 20hc or 4 days |
Are you thinking about running the Hoosier A6 tires? Lots of folks in SCCA stock classes are running those and doing very well.

My advice would be that if you're going to run on R compound DOT tires or slicks, you had better do something about making sure your oil pressure stays high enough. If I was going to track *my* car on such sticky tires, I'd probably fit one of the available deeper sump setups.

Not saying you are wrong, but I manage to make a set of MPSC last a full season here in Finland - that is 6 race weekends and several practice sessions in between the race weekends. |

Thank you for the link, interesting read.
At least one person on that discussion said that he drives them down to the cord, but it does look like most say max 35 - 40 heat cycles. |

If you really want the car and suspension to be track worthy, you'll have to go to full coilovers and then the car can be set up properly for race slicks. |
My experience? Not too much. Ive only done a season of autoX ( almost every weekend ) and a few 1.5 endurance kart races
Im usually in the top 3 or 4 with the SCCA or PCA in my class, but I have a lot more improving to do. I do understand it takes years to autoX well, and ive just started. I was hoping to slice off another 4-5 secs between sticky tires and suspension work, and develop more as a driver in the mean time. It looks a set of coilovers are what im looking for. Do the Hoosier A6s need 3 degs of neg camber? I dont know if GT3 control arms are in my budget this year. |
My advice is to spend the money on seat time until you are running near the top of your stock class. When you can drive better than the car, THEN start upgrading it.
This week, on the British tv show "5th Gear", they took a rookie driver and compared her lap times as follows: 1. Stock car 2. ECU upgrade for more power (no other improvements) 3. Aftermarket exhaust for more power (no other improvements) 4. Stickier tires (no other improvements) 5. Stock car with professional driving instruction Guess which was fastest? Yep, #5. At this level of the game, its almost all about the skill of the driver. |
The Hoosiers like -3 degrees, as do the Nitto NT01

Having said that, after spending a couple years doing auto-x on street tires, I immediately gained a couple of seconds when I moved over to Kumho Victoracers. Great for auto-x, no so great for DE's. Which raises another issue-- track tires need to get to their optimal heat range for maximum traction; I'm not sure how easy it is to get to those temps during an auto-x if you're doing single laps with a waiting period in between laps and ambient temps aren't in the 90's. |
