Default tire inserts

What tire inserts will work with the C27 takeoffs that will give the same basic characteristics as the premounts without the groove that developes on the inside edge of the tire. I know someone knows. Racing friend of mine says it's the insert in the premounts.

Try Echo High Traction Thin Yellows, will give better performance than the standard inserts. They tend to wash out the back end on corner entry.

The new CS-27W or Worlds premounts have eliminated that problem. I haven't had any problem with my newest set.

If you are running CS-27s for 6-12 runs you are on them for 3-8 runs to many!

Now I know why Brandon was so much faster! LOL

But really, you can try HPI greens also.


The premounted take-offs are about 2 to 3 tenths a alp slower after 2-3 runs. Then they should be practice tires or hand me overs to the new guys.

Hpi reds, oranges and yellows... depending on traction, you could try greens usually they have been too hard for me.

Trust me I know the tires I ran at the race were bought in Ga. in Oct 2004 so I guess they have upwards of 20+ runs!!!!! Guess I shouldn't complain.

2-3 they are definantly the best. I should have brought out the new set for the 3rd hean and A main but money is always tight. On the upside, my best lap was .4 slower than Brandon's best, so with new tires I'm only a tenth slower. excuses...excuses...excuses...

Default re-usability of inserts

generally, how many times can an insert be re-used? ... and what to look for before it gets chucked out

Default Am I correct in assuming

1. In general you use a softer insert with colder use (lower number tires) tires and firmer inserts with hot wheather tires?

2. If you are compeating on a national level, then maybe you use a set of tires for 3 or 4 runs, but on the local club level most people are not shelling out $30 a week to run new tires every weekend.

All of my TO27's from Reedy have very minimal grooves even afte running them this past winter. The key is to not run excess camber or caster especially in the front. The tires are faster this way too. When Masami posted his set up last year he was running nearly flat camber at -.5degrees.

I have NEVER seen that dramatic off a drop on these tires after 3-4 runs...never! If anything they seem better as they wear in...Now I run on 2 tracks...a very high traction permanent facillity and a parking lot track that is "less than perfect" and I can get 20 runs easy. And mine don't show any problems until they actually wear out. I think we really scare newer racers off by telling them a 35-40 dollar set of tires/wheels will wear out in less than one day of racing...it simply isn't true. I don't know many newbies that can drop 80 bux worth on tires every race day.

Now granted, maybe at the highest level of racing where 1/10 of a second seperates the field...then yes, I'm sure it matters...but that's about it.

I have never had a problem spending whatever it may take to be at the top, and if it were truly 2-3 tenths off after 3 runs, I would definately keep new treads on all the time, but I have never encountered this...

As for inserts...I like the Mediums that come with it...a slightly firmer insert will help with the inner groove problem, as will running a 1/2 less neg camber, but I haven't seen that problem with a properly set up car. Shoot, I've seen the old cheap open cell foam inserts work awesome on a very cold track.
