Happy Mother’s Day to all you Mom’s out there from JTL Performance.
You should do something nice for yourself this year.

Buy a set of our B-Square Set Up plates for the racer in you life.

This would make all of those late night set up things a simple one person job, so you would never get dragged down to the cold shop at midnight in your Pajamas to help set front end toe again.😂

We have the plate sets in stock and ready to ship or pick up at your local track for $200 plus tax.
Please contact us if you have any questions
Thx

Some tear downs are just tougher than others.
Had to finish up with a carbide blade on a Sawzall followed by a big hammer and some real persistence.
Lots of clean up and inspection to follow 👍

Now what are you doing and why does the shop smell like vinegar?
Are you dying Easter eggs?
Nope
Just more block prep.

Unbelievable amount of stuff stays stuck in the coolant passages of these almost 50 year old core engines.
We use a special proprietary blend of products and soak the block overnight.
Just check out what’s in the bucket that came out of an already “cleaned” block.

This is the kind of attention to detail you get from JTL Performance.

We did not dye eggs but we do hope you all have a great Easter.
