Hoosier G60 tires: $103.50; 110 Race Gas: $8 per gallon; Methanol: $4 per gallon. We have a full line of racing parts at deeply discounted prices!! We accept all major credit cards. Give Trevor a...

New to 4/4 and trying to figure out exactly what the effect is on entry, middle and exit of a stiffer left rear spring.

IMO, you will want to consistently turn around 7200 to compete with the crate. That is the RPM range we ran. I am a big believer in the 487x heads. Mostly because that was what we ran and our...

sorry mod88s, but I 100% disagree with what you are saying. We ran a 300 pound right front spring last year in a 2 link and had a ton of forward bite. We also ran a 125 pound left rear spring. You...

We have an open motor, but have 7 1/2 inches of rake in our jbar. How low are you on the pinion side?

Another thing you could do is soften your right rear spring a little when the track slows down. Our big change we would make with our 2 link was drop right side bar and lower right rear spring rate...

I wonder if the spring is just compressing and not actually driving the tire into the ground. Not sure as we are very new to this. With our car we are running a 225 RR with a 3/4 shock and...

We turned our motor around 1,000 more RPM more than the crates to have similar power. That was with a Schmidt machine engine with 487x heads. We probably didn't need to go to that extreme, but the...

What are you running for a right rear shock, spring and bar angles?

We ran 300 pounds of bite all the time in our 2 link stuff and always had good forward bite.

Jeff,I honestly think that is a really good point that especially in a mod if the top line is fast you have to get up there and go with it. Trevor prefers to run the low line, but he has realized...

Jeff,It has been hard at Eagle with entry to 1 being so rough consistently this year. We tried a 3 compression, 6 rebound shock racing at another track to keep the car on the right rear, but hard to...

Unless he is footing the bill for a good part of your racing budget I would seriously consider changing crew people. Another option would be to send him to one of the suspension schools so he better...

275 at least, bigger the better is what I always say.

The left side bar on a 3 link creates antisquat as you increase angle which puts traction into the left rear tire. It also raises that corner of the car. As a bi product it also creates roll steer...

On a chevelle stub I would not run stiffer than 550 on RF. Go softer from there to free entry/middle. There is a huge fallacy that you need a big RF spring to help a 2 link get off the corner. ...

Sounds like a softer right front could help fix your issue. What stub are you on? Also raising your right side bar a hole or two will assist with loosening the car throughout the corner, but...

Alright I have heard recommendations from as low as 4.86 (with crate I assume) up to 5.14. Has anybody ran there with a 5.29 before in a mod or close to it?

Whats an A mod? Have you been spending time with super Dave? :) By A mod, I meant an IMCA modified as opposed to an IMCA sport modified we ran last year.

That is what we do also. Have to grease the wheel bearings if you run innner axle seals. Good news is no oil on your brake rotors and mess everywhere.

Definetly not crazy at all, last year at Septemberfest, Tyler Frye was nearly a second faster than the top A mods at the end of the night. He was running mid 19's at Beatrice and the A mods were all...

More bite is what I would do. I would add at least 100 pounds of bite.

Yep, 4/4 for us this year. Should be fun, we have a 5.29, just trying to figure out if that is too much gear for Oski. Don't mind bumping the chip a little, but just don't want to be up against it...

Thinking of trying and running all the nights of the frostbuster in Iowa. What gear for an Open motor with a mod at Oski, Marshalltown, Boone and Vinton?

What have you guys found to be the optimum operating temperature for the IMCA Hoosier G60s?I know you dont want more than about 10-15 degrees difference in left rear to right rear temperature, but...
