ROW M030 suspension stiff enough for slicks?

[Topless]

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. 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.

What is this based on? Do you have some documented information on this or is it based on your personal experience?

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.

Lap times just begin to fall off after about 20 HC here in SoCal. By 30 HC they might be 2-3 seconds slower. They still have tread material but they are no longer fast. It's like losing 50hp. We have very high track temps here in the southwest so you may be able to run a bit longer in Scandinavia but 30 HC is surely outside the sweet spot. This is pretty well known:

I agree with Topless' advice. The ROW M030 suspension can't be set up to take maximum advantage of a true slick and therefore, you won't see the benefit that you might be expecting. A good DOT R-compound tire is your best bet with the M030.

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.
